Abstract

This study examines the systematic violation of labor rights in the civil construction sector of the Amazonas region, Peru, focusing on persistent non-compliance with collectively negotiated wage scales despite existing legal frameworks. Drawing on empirical data from structured surveys administered to 142 construction workers and qualitative analysis of administrative and judicial records from the Regional Labor Directorate (2012–2015), the research finds that 99.3% of workers received wages below collectively agreed rates, while 84.5% filed labor inspection requests and 85.5% pursued administrative conciliation. Nevertheless, 95.3% of judicial claims proved unsuccessful, primarily due to employer evasion strategies — including consortium structures without solidarity clauses and deliberate concealment of attachable assets — resulting in enforcement proceedings averaging 36 months without effective wage recovery. To address this structural enforcement deficit, the study proposes a mandatory guarantee letter mechanism for construction projects exceeding 50 Tax Units (UIT, approximately USD 53,000), issued in favor of administrative labor authorities, to secure wage and social benefit obligations prior to project commencement. This proposal is grounded in a comparative legal analysis of guarantee requirements already operative in regulated sectors, including public procurement, postal services, vehicle inspection centers, and renewable energy generation. The theoretical framework integrates Reale's three-dimensional theory of law, the public service doctrine, the ILO's decent work standards, and Bandura's sociocognitive theory of moral disengagement. The findings demonstrate that current administrative and judicial mechanisms are structurally insufficient to protect construction workers' rights, and that preventive enforcement instruments — operating on employers' economic interests before violations occur — offer superior protective efficacy than purely reactive sanctions.

1. Introduction
The Sustainable Development Goals (SDGs) offer the construction industry a new perspective through which global needs and wants can be translated into business solutions . The construction industry in emerging economies is significantly influenced by the informal sector, characterized by informal employment and weak regulatory oversight . The construction and building operation sector is responsible for 40% of all energy-related carbon dioxide (CO2) emissions worldwide, facing challenges to improve its image, sustainability performance and human value , in order to minimize the negative impacts of the construction industry on the environment. the economy and society . However, the construction industry has been slow to implement safe working conditions, although this could reduce risks and hazards to people's health and safety ; moreover, this sector frequently operates in precarious working conditions, characterised by systematic violations of fundamental labour rights .
Previous research has documented similar patterns in Latin America, where construction workers constitute one of the most vulnerable occupational groups, experiencing high rates of informality, occupational hazards, and labor rights violations .
In Peru, the construction sector contributes significantly to the Gross Domestic Product (GDP), but this impact depends on some factors such as low budget execution and economic instability . Similarly, construction workers in Peru are subject to a special labor regime established through collective agreements that determine salary tables, benefits, and working conditions . Despite legal frameworks designed to protect these rights, empirical evidence suggests persistent non-compliance by employers, especially in peripheral regions where oversight by labor authorities remains limited.
The Amazon region exemplifies precisely this problematic reality. Located in northern Peru, this geographically dispersed region has received significant public and private investment in infrastructure projects, leading to considerable demand for construction labor. However, workers in this sector suffer from systematic underpayments, denial of social benefits and insufficient working conditions.
Collective bargaining in the Peruvian construction sector has historically established comprehensive wage tables that specify remuneration according to categories of workers: workers (peons), skilled workers (journeymen) and operators (operators) . These agreements, published annually by ministerial resolutions, constitute binding legal instruments. However, implementation mechanisms have proven to be insufficient. The structure of the administrative labour authority comprises regional labour directorates and decentralized employment promotion zones, which carry out labour inspections and administrative conciliations. However, these procedures rarely result in effective recovery of payments for workers.
The conventions of the International Labour Organization, in particular Convention 95 on the Protection of Wages and Convention 154 on Collective Bargaining , set out fundamental principles to ensure that workers receive agreed remuneration. The International Labour Organization's (ILO) decent work agenda emphasises productive employment with fair incomes, job security, social protection and respect for rights . Peru has ratified these conventions, incorporating them into national legal frameworks through Article 55 of the Constitution . Despite this normative basis, gaps in implementation persist.
This research examines the structural factors that contribute to labor rights violations in the construction sector of the Amazon region and proposes a guarantee mechanism based on a letter of guarantee to ensure compliance with wage obligations. The study addresses three key issues:
What factors explain the persistent non-compliance with salary tables despite existing legal frameworks?
How effective are the current administrative and judicial enforcement mechanisms to protect the rights of construction workers?
Can a mandatory guarantee instrument issued to labour authorities provide more effective labour protection?
The research basically contributes to research in labor law by analyzing deficiencies in the application of special labor regimes and proposing innovative guarantee mechanisms applicable to this type of vulnerable sectors. In addition, it provides empirical evidence on the experience of construction workers in administrative and judicial proceedings, documenting systemic failures in the protection of labour rights. Finally, the proposed bank letter of credit mechanism is based on the comparative analysis of collateral requirements in other regulated sectors, offering a viable policy intervention.
2. Theoretical Framework and Literature Review
2.1. Three-dimensional Theory of Law
The three-dimensional theory of law was developed in a prominent way by Miguel Reale , who conceptualizes legal phenomena through factual, normative, and axiological dimensions. The factual dimension recognizes law as a social phenomenon, which manifests itself daily in human social interactions and relationships. This sociological perspective emphasizes the omnipresence and interconnection of law with economic and political phenomena. The normative dimension addresses the prescriptive nature of the law, establishing standards of social conduct through legal norms that specify the legally required conduct. The axiological dimension conceives of law as a value that pursues higher values such as human dignity, justice and social welfare.
This tripartite framework is especially relevant for analyzing labor rights violations in construction. The factual dimension manifests itself in empirical patterns of systematic underpayment of wages, while the normative dimension includes constitutional provisions, international conventions, and collective agreements that establish workers' rights. The axiological dimension refers to fundamental values of human dignity, decent work and social justice that labor law seeks to protect. In fact, effective labour regulation requires coherence in these three dimensions.
2.2. Public Service and Administrative Function
The theory of public service, developed by French academics of administrative law such as Maurice Hauriou and León Duguit, conceives of public administration as oriented to the collective satisfaction of necessary needs. Hauriou emphasized public service as an organizational reason, while Duguit articulated public service as the defining criterion of administrative activity, linked to the general interest . This theoretical framework implies that labour authorities must effectively protect workers' rights as a public service obligation.
The concept of public service incorporates principles of continuity, adaptability and equality . Applied to labor management, these principles require the consistent application of labor standards, adaptation to changing labor realities, and equal protection for all workers, regardless of sector or region. When administrative mechanisms fail to guarantee the payment of wages, the public service remains unfulfilled, creating legitimacy deficits and eroding workers' trust in state institutions.
2.3. Decent Work Framework
The ILO's concept of decent work, introduced by Director-General Juan Somavia, structures four main pillars. The first of these pillars is the work or employment itself. The second is represented by labour rights, especially fundamental rights: freedom of association, the right to collective bargaining and the eradication of forced labour, discrimination and child labour. The third pillar has to do with the notion of social security and protection; While the perennial demand for security reflects a basic human need, many find themselves in situations of insecurity and precarious employment: 80 per cent of the global labour force lacks social protection, unemployment benefits or other forms of social assistance. The fourth pillar, finally, focuses on the idea of representation and social dialogue. How people can make their voices heard is a key aspect of the notion of decent work, and social dialogue is the mechanism that helps advance the other three dimensions of decent work . Decent work encompasses productive work in conditions of freedom, equity, security and human dignity, with respected rights and adequate remuneration. Amartya Sen emphasizes decent work as a right that transcends current labor legislation, recognizing the basic rights that inform institutional and policy design .
According to the above conceptualization, the key dimensions of decent work include freedom of choice of employment, productive employment that provides acceptable livelihoods, fairness of treatment and opportunities, protection of job security, and respect for human dignity. Productive employment is essential for workers and families to achieve an acceptable standard of living, while enabling enterprises and countries to achieve sustainable competitive development. When construction workers are systematically paid wages below negotiated levels, several dimensions of decent work are violated.
2.4. Principles of Wage Protection
International and national legal frameworks establish that wages are of a food nature, that is, they constitute the main means of subsistence of workers. ILO Convention 95 on the Protection of Wages sets out fundamental principles such as payment in legal tender, direct payment to workers, regular pay intervals and restrictions on wage deductions. ILO Recommendation 85 complements these principles with detailed implementation guidance .
Article 24 of the Political Constitution of Peru declares priority in the payment of remuneration . Supreme Court jurisprudence consistently affirms the alimony nature of wages, establishing their privileged status in credit ratings and emphasizing state obligations to ensure effective payment . Despite this strong regulatory framework, enforcement mechanisms are often insufficient, especially when employers lack peggable assets or resort to manipulating the corporate structure to evade obligations .
2.5. Sociocognitive Theory
Albert Bandura's sociocognitive theory includes mechanisms of moral disconnection that individuals use to carry out unethical behaviors while maintaining positive self-esteem. These mechanisms include moral justification, euphemistic labeling, advantageous comparison, displacement of responsibility, diffusion of responsibility, distortion of consequences, dehumanization, and attribution of blame . Employers who fail to comply with labour obligations frequently employ these mechanisms, justifying non-compliance through financial constraints, minimizing the severity of violations, or attributing liability to subcontractors.
In the context of the construction sector, moral disinterest manifests itself when employers justify underpayment of wages as economically necessary, characterize workers as temporary or unskilled to justify lower wages, or structure complex corporate arrangements to conceal liability. Understanding these psychological mechanisms helps explain persistent violations despite workers' awareness of their rights and the availability of grievance mechanisms. Effective interventions must address not only legal compliance, but also organizational cultures that facilitate moral disinterest .
2.6. Background
Syed's 2023 manuscript offers a qualitative exploration with the aim of proposing effective strategies to improve compliance and enforcement of labour laws in Bangladesh, reducing incentives for non-compliance. The study is based on primary data obtained from statutes and court decisions, as well as secondary data from academic articles, books, and book chapters, among others. Through a cost-benefit analysis from the employers' perspective, the study argues that showing the higher costs associated with violating labor laws, compared to the benefits obtained, will incentivize employers to prioritize compliance to safeguard their interests. To this end, the research proposes eight different techniques or mechanisms to limit the benefits derived from non-compliance with labor laws. These strategies are carefully organized into two categories: "increase the likelihood of voluntary compliance" and "support from other actors." It concludes that the proposed techniques to improve compliance and enforcement of labour laws in Bangladesh have great potential to benefit key stakeholders, policymakers and practitioners in the sector. In addition, the study's findings have valuable implications for other developing countries in the South Asian region, given their similar socioeconomic and cultural contexts.
Ramdan in 2024 , argues that workers and employers, when conducting labor relations, must comply with labor standards, which include labor standards and occupational safety and health standards. The implementation of labour standards in the workplace requires the role of labour inspectors in supervision. The research problem was: What is the labor inspection mechanism for the implementation of labor standards in the workplace? This research was of a legal normative type with a statutory approach, data collection through bibliographic research and data analysis carried out in a descriptive way. The results indicate that labour inspections relating to the implementation of labour standards in the workplace are carried out by labour inspectors under the authority granted by Article 176 of Law No. 13 of 2003 on Employment. It concludes that labor inspectors carry out labor inspection mechanisms for the implementation of labor standards under the provisions of Articles 4 to 51 of the Regulations of the Minister of Manpower of the Republic of Indonesia No. 33 of 2016, which consists of the planning stage, the implementation stage, and the reporting stage.
Tchawouo in 2025 set out to strengthenlabour enforcement mechanisms to ensure social justice for employees. Through a documentary review, it examined the implementation mechanisms provided for in the Basic Conditions of Employment Act 75 of 1997 (BCEA) and the Employment Equity Act 55 of 1998 (EEA) and assessed their effectiveness in making the promise of labour rights a reality. It explores the conceptual underpinnings of social justice, describes the institutional and procedural frameworks for law enforcement, and analyzes jurisprudence to highlight systemic challenges. It also compares South Africa's implementation regime with international practices and makes practical and strategic recommendations for reform. In its results, it indicates that, in 2008, the ILO adopted the Declaration on Social Justice for a Fair Globalization, a soft law instrument that imposes on its member States, including South Africa, the obligation erga omnes to harmonize their domestic legal system with international labor standards in terms of conditions of employment, labor equity, occupational safety and compensation for accidents. However, employers' non-compliance with regulations is endemic in developing economies, constituting a structural obstacle to social justice. It concludes that in view of the insufficiency of the deterrent of the pecuniary and custodial sanctions in force, the doctrine advocates the implementation of coercive mechanisms of an administrative nature with a direct impact on the economic interests of the offender, such as disqualification from contracting with the State, exclusion from public subsidies and the suspension or closure of the establishment. measures that would operate as labor compliance instruments of greater preventive and corrective effectiveness.
Kaium and Ahsan in 2025 in Bangladesh, studiedlabour inspections and occupational safety: lessons learned to improve regulatory frameworks and interventions. They did this by collecting primary data through interviews with relevant stakeholders, such as officials from the Department of Inspection of Factories and Establishments (DIFE) and representatives of workers' and employers' organizations, to obtain various views on the effectiveness of the interventions. The secondary data was collected from the annual report of the Department of Inspection of Factories and Establishments (DIFE) and the labor inspection report. In their results, they revealed varied consequences of the enforcement agency. Some DIFE interventions have a positive correlation, others have a negative correlation, and some have no correlation with the overall results of the DIFE in terms of compliance with occupational safety and health standards in factories and worker well-being. In conclusion, the DIFE should consider implementing a more targeted approach that is in line with global safety standards. This involves expanding the scope of inspections, improving the implementation of digital tools such as the Labour Inspection Management Application (LIMA) and giving local DIFE officials the necessary decision-making authority, in order to facilitate rapid and sector-specific measures.
Do Prado et al. In 2025 , they studied the application of labor regulations and outcomes for firms: Evidence from Brazil. Using a unique set of administrative data that includes information on labor inspections, employer-employee matched data (RAIS), and data from the Central Bank of Brazil's credit registry, the paper presents novel findings on the post-inspection dynamics at the firm level within the highly regulated Brazilian labor market. Employing a difference-in-differences approach, it observes an increase in formal employment without any immediate impact on income, suggesting that inspected firms tend to formalize their unregistered workers after an inspection. However, the results also reveal a large negative impact on the company's performance and a higher likelihood of long-term closure, indicating that audited companies are struggling to offset the costs of formal labor. In addition, it notes that the companies inspected face tighter credit conditions, underscoring the broader economic implications of the application of labour standards. When analyzing the heterogeneity between municipalities, it found that the adverse effects of inspections are more pronounced in areas with lower rates of informality. In conclusion, the research contributes to understanding how the application of labor law affects business dynamics, offering perspectives on the dilemmas faced by companies in highly regulated environments.
Martinelli et al. In 2025 in their article they explored the challenges that these changes pose to labour inspectorates, as well as the strategies they have adopted to address them, through a systematic and narrative review of 75 articles, books and book chapters published between 1990 and 2023 in the field of labour relations. They identified a significant impact of structural transformations in the labour market (globalisation, tertiarisation, digitalisation, demographic and political changes) on the fragmentation of business organisation and labour relations. In response, labor inspectorates have implemented three types of strategies: (1) internal restructuring; (2) diversified and blended approaches to workplace monitoring; and (3) cooperation with other regulatory bodies. They conclude that the labor inspectorate faces a structural deficit of resources aggravated by austerity policies, which compromises its coercive capacity and legitimizes the adoption of strategic regulatory governance that prioritizes interventions based on data analysis, inter-institutional cooperation and regulatory co-execution with union actors. The effectiveness of the inspection system depends on political support for the regulation of the labour market and on a consolidated legal-institutional framework that allows for the articulation of joint enforcement mechanisms between inspectors, trade unions and other interested parties. It is imperative that the labour inspectorate transcends its merely supervisory role to assume a transformative role in the protection of fundamental labour rights, coherently integrating itself into the public policy of labour market supervision. Finally, they recognize the need to deepen comparative research between legal systems, in order to identify strengths and limitations of each regulatory strategy, particularly those that promote the active participation of workers as subjects of law in the inspection processes.
Picco in 2025 in its study on thesystem of inspection and application of labour legislation in Italy, examines Decree-Law No. 19/2024 (transformed, with amendments, into Law No. 56/2024), which introduced changes in two important aspects of labour sanctioning law. On the one hand, the institutional structure of the labour inspectorate was reviewed, thus completing a reform process begun twenty years earlier with Legislative Decree No. 124/2004. On the other hand, in response to public outrage over the tragic workplace accidents that received widespread media coverage, the sanctioning framework for subcontracting was modified. This includes the reintroduction of criminal sanctions, thus reversing the decriminalisation introduced eight years earlier by Legislative Decree No. 8/2016. It concludes that it is clear that the legislature has subordinated the protection of workers affected by subcontracting agreements to the imperative need to respond to public outrage following a series of tragic accidents at work, effectively instrumentalising criminal sanctions to assuage widespread concerns about the perception of insecurity in the workplace.
Negi and Sharma in 2025 , in their study on the challenges of Labour Law in the Construction Industry: Safety, Welfare and Wages, critically analyse the difficulties faced by construction workers in relation to social benefits, fair remuneration and workplace safety. Under a desk analysis, it examines the shortcomings of the legal framework, including low registration rates with state social welfare boards, a shortage of enforcement tools, and the misappropriation of public funds. While the efforts of civil society organizations and the courts have raised awareness, they are not enough to implement systemic change. The importance of unionization and high safety standards is highlighted in the study, which compares construction labor practices in India with international standards, particularly those seen in countries such as Canada. They conclude, suggesting policy changes, such as mandatory safety training, digitization of worker registration, tightening inspection procedures, and effective use of the welfare tax through Direct Profit Transfer (DBT) systems. Providing construction workers with decent working conditions is not only a legal necessity, but also a humanitarian and constitutional necessity. The lives of millions of people in industry can be greatly improved by strengthening enforcement of existing standards and fostering a culture of accountability.
Simon in 2021) , argues that the construction sector requires special attention from labour inspectors, as it is prone to phenomena such as serious occupational accidents and social dumping. In the industrial field, on-site inspections are crucial moments for the implementation of labour legislation. In carrying out inspections, labour inspectors assess a wide variety of situations and attempt to determine appropriate measures. The unpredictability of the sector forces them to constantly adapt to new situations and to resort to their discretionary power, which in the literature has been described as responsive regulation. Under these arguments, the study focuses on the decision-making processes of inspectors when carrying out welfare and anti-fraud inspections in this specific sector. Based on 34 interviews with Belgian labour inspectors and experts, identifying five logics that help to make decisions and justify them later. These logics are based on five dimensions inherent to the work of inspectors: procedures, values, experience, relationship with those inspected and relationship with colleagues. By referring to such logics during inspections, inspectors tend to privilege certain types of results as they pursue their cases. It concludes that there is a tension between regularization and legal procedures in the inspection work.
3. Materials and Methods
3.1. Research Design
This study adopts a mixed methodological approach of convergent type, which systematically integrates quantitative data obtained through a structured survey applied to 142 workers in the construction sector, with qualitative analysis of administrative and judicial records from the competent entities of the Amazonas Region, Peru. The methodological triangulation between both sources, both primary and documentary, allows not only to describe the phenomenon of wage non-compliance, but also to explain its structural determinants and evaluate the effectiveness of the existing protection mechanisms, providing the study with greater internal coherence and construct validity.
The research was carried out between January and September 2015, focusing on civil construction workers employed in projects that exceed 50 Tax Units (UIT), equivalent to approximately 192,500 soles or 53,000 USD at current exchange rates . This threshold is not arbitrary, since projects of this magnitude presuppose sustained labor relations, differentiated occupational categories, and more complex conventional obligations, which makes them the most representative scenario of the systematic violations under study.

3.2. Sampling Strategy
A non-probabilistic convenience sample was selected with intentional criteria, composed of 142 civil construction workers from the provinces of Bagua (34.5%), Chachapoyas (32.4%), Utcubamba (19.0%), Bongará (8.5%) and others (5.6%) . The choice of a non-probabilistic design is justified for three converging reasons. First, the absence of a complete and updated sampling framework of civil construction workers in the Amazon Region, which makes classic probabilistic sampling technically unfeasible, a recurrent situation in research on informal labor markets in developing economies. Second, the object of study aimed at workers with direct experience in disputes over salary payments and in the use of administrative or judicial complaint mechanisms, requires an intentional selection that guarantees the substantive relevance of the informants, instead of random statistical representativeness. Third, studies on labor compliance in highly informal sectors require access strategies based on institutional networks, such as unions, inspections, workers' associations, precisely because the target population tends to be invisible to conventional census frameworks.
The inclusion criteria applied were: (a) employment in civil construction projects in the last 12 months; (b) documentable personal experience in wage payment disputes; and (c) direct knowledge of the administrative or judicial complaint procedures. These criteria ensure that the informants have the necessary experiential capital to respond with content validity to the instruments applied.
The main limitations of non-probabilistic sample design involve generalization constraints that must be transparently recognized. The results are not statistically extrapolated to the national universe of construction workers, or even to the whole of the Amazon Region in periods other than the harvest. In addition, the selection bias inherent in the workers who participated is those who had already activated grievance mechanisms, which distinguishes them from those who, out of disappointment or ignorance, opted for inaction, which may underestimate the real magnitude of non-compliance in the sector. However, these limitations do not invalidate the findings, because the internal consistency of the data, their convergence with the comparative literature, and the triangulation with independent administrative records provide the results with sufficient analytical strength to support the proposed conclusions.
3.3. Data Collection Instrument
In the case of primary data collection, it was carried out through a structured self-administered questionnaire with the assistance of the researcher, designed specifically for this study and validated by expert judgment before its final application. The instrument was administered through individual communications, ensuring the understanding of each item and reducing socially desirable response bias.
The questionnaire was organized into five thematic modules, each associated with specific measurement variables:
1) Module I collected sociodemographic and occupational variables: sex (92.3% male; 7.7% female), age (distributed in the ranges 17–20 years: 9.9%; 21–39 years: 53.5%; 40–59 years: 36.6%), occupational category (worker: 68.3%; journeyman: 20.4%; operator: 11.3%) and marital status (cohabiting: 40.1%; married: 29.6%; single: 22.5%; others: 7.7%) . These variables allow us to control for the internal heterogeneity of the sample and to contextualize the family dependence on labor income.
2) Module II measured compliance with the salary payment through: conformity of the salary received with the collectively bargained table, payment method received (regular salary, piecework/piece, tips, others) and periodicity of payment.
3) Module III assessed access to training and awareness of rights: receipt of training from the employer (yes/no), content of training received (technical skills, labour rights, collective bargaining, social benefits) and level of self-reported knowledge on fundamental labour rights.
4) Module IV analyzed the behavior in the event of non-compliance: chosen complaint instance (Regional Labor Directorate, Ministry of Labor, decentralized zone, none), use of specific procedures (labor inspection: yes/no; administrative conciliation: yes/no; judicial complaint: yes/no) and perceived result of each mechanism (successful/unsuccessful).
5) Module V collected perceptions of the proposed guarantee mechanism: support for the implementation of a guarantee instrument (yes/no), preference over ownership of the instrument (administrative authority vs. individual workers) and reasons for the preference expressed.
For the analysis of administrative records, formal reports from the regional labor authorities were obtained and systematized documenting the inspection and conciliation procedures developed between 2012 and September 2015. For the Regional Directorate of Labor, with jurisdiction over the provinces of Chachapoyas, Luya-Lamud, Rodríguez de Mendoza and Bongará, the inspection records revealed an exponential escalation, from 1 case affecting 15 workers (2012), to 6 cases with 49 workers (2013), 4 cases with 81 workers (2014) and 30 cases with 800 workers between January and September 2015 . The decentralized employment zone Bagua-Utcubamba documented parallel trends, with cases rising from 3 (2012) to 16 (2014) and 24 in the partial year 2015 . Thus, the administrative conciliation records of 2014–2015 showed high rates of non-compliance with conciliated agreements by employers and high employer non-attendance at hearings, which is in itself an indicator of the coercive weakness of the system and a factor that precipitated the escalation towards judicial proceedings.
For the comparative legal analysis, the existing guarantee requirements in the regulated sectors were examined, including:
State contracting contracts (Legislative Decree 1017 , Law 30225 ).
Postal Service Concessions (Supreme Decree 032-93-TCC ).
Vehicle Technical Inspection Centers (Supreme Decree 025-2008-MTC ).
Issuance of driver's licenses (Supreme Decree 040-2008-MTC ).
Renewable energy generation (Supreme Decree 050-2008-EM ).
This analysis identified common characteristics of letters of guarantee, including irrevocability, solidarity, unconditionality, immediate enforceability, and issuance to regulatory authorities.
3.4. Ethical Considerations
The study was conducted in full observance of the fundamental ethical principles applicable to research with human participants. Prior to the application of the questionnaire, each worker received complete information about the objectives of the study, the voluntary nature of their participation, the absence of labor or administrative consequences derived from their response, and the exclusively academic use of the data collected. On this basis, the informed consent of each participant was obtained, in accordance with the ethical standards of research in social and legal sciences.
The confidentiality of the data was guaranteed by the anonymization of all responses from the collection phase, where no questionnaire contains information that allows the individual identification of the worker, and the data were processed in an aggregated manner. This measure is especially relevant given the context of labor vulnerability of the informants, who could have been exposed to retaliation by employers in the event of possible disclosures of their claims or perceptions. The protection of the participants from possible harm arising from their collaboration in the study was an essential methodological and ethical priority, in line with the principles of non-maleficence and justice that guide research in contexts of social vulnerability, as recognized by the ILO's doctrine of decent work.
3.5. Data Analysis
The quantitative data were analyzed using descriptive statistics that include absolute and relative frequencies, organized in distribution tables, which allow for a precise systematization of the magnitude of wage non-compliance, the sociodemographic and occupational profile of the affected workers, and the patterns of use of the available protection mechanisms. This level of analysis is consistent with the characteristics of the methodological design adopted, based on exhaustive documentary analysis of the thesis without generating additional primary data and with the central purpose of the study, to describe and legally interpret phenomena whose magnitude is already analytically conclusive by itself.
Thus, frequency distribution tables and proportions were constructed for each key variable of the study such as salary compliance, payment modality, access to training, complaint mechanisms used and results obtained, allowing the systematic comparison between occupational subgroups (workers, journeymen and operators) and the identification of patterns of concentration of non-compliance in certain categories of workers.
Second, comparative tables were developed to contrast structurally related variables, such as the rate of use of tutela mechanisms, the rate of successful results, the escalation of documented inspection cases (2012–2015) and the marginality of the penalties effectively collected. These comparative tables allow for a precise quantification of the gap between formal access to labour justice and effective protection of rights, without the need for statistically significant tests, given that the magnitude of the differences observed is, in legal and social terms, self-evident and can be interpreted directly from the descriptive analysis.
Thirdly, the qualitative analysis of the administrative records was carried out through inductive thematic coding, where recurrent emerging categories were identified from the systematic review of the inspection and conciliation files, circumvention through consortium structures without solidarity, absence of seizable assets, dilatory litigation by the employer, non-compliance with conciliated agreements, verifying their saturation through longitudinal analysis of the records of the period 2012–2015.
Finally, the methodological triangulation between survey data, administrative records, and comparative scientific literature operates as a cross-validation mechanism that raises the reliability of the findings beyond what each isolated source could sustain, guaranteeing the analytical coherence of the study from a critical and legally grounded perspective.

The results of the survey reveal a massive and systematic violation of the fundamental right to fair remuneration. Out of 142 respondents, 99.3% received salaries below the collectively bargained tables, while only 0.7% received remuneration according to the agreed scales . This almost universal non-compliance cannot be described as an isolated infraction, but as the empirical expression of a structural fracture in the factual dimension of the labor legal system, in accordance with Reale's three-dimensional theory of law, where he maintains that the norm exists and the values that inspire it are recognized, but its social materialization is practically non-existent.
From the perspective of Bandura's sociocognitive theory, this pattern responds to institutionalized mechanisms of moral disconnection such as economic justification, diffusion of responsibility, and minimization of consequences, through which employers perpetuate wage underpayment while maintaining a self-perception of corporate legitimacy. Negi and Sharma confirm this phenomenon in the construction industry, documenting how organizational cultures that normalize infringement operate as vectors of systematic reproduction of non-compliance.
In turn, Syed demonstrates that when the costs associated with the regulatory violation are lower than the benefits obtained by the non-compliance, the employer's economic rationality is structurally inclined towards the violation, configuring what this study identifies as an institutionalized illicit rationality. This situation is aggravated by the fact that 16.9% of the workers were compensated through piecework agreements, which is a modality that transfers the productive risk to the worker, despite being entitled to weekly wages by occupational category. This practice constitutes a circumvention of the special labor regime of the construction sector, emptying of content the normative protections of ILO Convention 95 and the constitutional mandate of Article 24 of the Political Constitution of Peru, which recognizes the nutritional and priority nature of remuneration.

Note. It shows that the educational deficit operates as a mechanism of informational asymmetry.
The training deficit found with 66.2% of workers who did not receive any training from the employer, and the existing training was limited to general technical skills , is not a mere business omission, but a functional mechanism for perpetuating the informational asymmetry that sustains the cycle of labor violations. From Reale's three-dimensional theory, the axiological dimension of law oriented to human dignity and social justice, requires that knowledge of labor rights be a precondition for their effective exercise; its deliberate absence operates as a structural obstacle to access to justice.
This result is directly articulated with the mechanisms of moral disconnection by dehumanization and attribution of blame described by Bandura: by keeping workers in a state of legal ignorance, employers implicitly shift the responsibility for non-compliance to those who do not complain, making invisible the unlawful nature of their conduct. Negi and Sharma identify this same pattern in India, noting that low registration rates in social welfare systems are partly due to the systematic misinformation of workers as a strategy to evade employer obligations.
The absence of training in collective bargaining, pay scales and social benefits compromises the ILO's fourth pillar of decent work, known as representation and social dialogue, by depriving workers of the cognitive tools necessary to assert their rights in labour consultation spaces. As Amartya Sen argues, decent work transcends positive norms and requires the institutional design of real conditions for the exercise of rights, including effective access to legal information.

Note. Evidencing structural inefficiency of the inspection system
The high rates of use of the available administrative mechanisms, according to 84.5% of workers who submitted requests for labor inspection and 85.5% resorted to conciliation , show an active legal awareness among workers and their willingness to exercise their rights through formal channels. However, as Martinelli et al. The mere use of the mechanisms does not translate into protective effectiveness when the inspection system operates with a structural deficit of resources and a reactive and improvised governance.
The predominance of complaints to the Regional Directorate of Labor (69.0%) compared to decentralized areas (6.3%), which support accusations of corruption , reflects a selective erosion of institutional legitimacy that concentrates the burden of the system in a single entity, reducing its real operational capacity. This phenomenon is part of what the theory of public service calls non-compliance of the public function, which occurs when the labor administration does not guarantee continuity, adaptability and equality in protection, generating legitimacy deficits that discourage reporting, as illustrated by the 11.3% who chose not to file complaints, out of disappointment in the face of administrative inefficiency .
In this regard, Ramdan confirms that inspection effectiveness requires a coherent articulation between the planning, implementation, and reporting stages; its absence turns procedures into formal rituals with no real corrective capacity. Do Prado , on the other hand, document that even in contexts where inspections manage to formalize unregistered workers, the effects on sustained wage compliance are limited when they are not accompanied by effective asset monitoring and enforcement mechanisms.

Note. It shows procedural delay and asset concealment through consortium structures.
The judicial failure rate of 95.3% among those who filed legal claims configures what from the theory of public service must be qualified as a material and systematic denial of labor justice. The fact that 74.6% of workers have gone to court after unsuccessfully exhausting administrative mechanisms reveals that the labor protection system does not operate as a coherent set of staggered compensations, but as a succession of formally authorized, but substantively ineffective, instances.
The factors that explain this jurisdictional collapse are multidimensional. In the first place, the average duration of the proceedings, which amounts to 36 months in total, constitutes a structural procedural delay that, by itself, operates as a mechanism for the denial of justice by compromising the alimony and urgent nature of the wage credit recognized by ILO Convention 95 and the jurisprudence of the Peruvian Supreme Court. Second, the concealment of assets through consortium structures deprives favourable judgments of enforceable content, transforming the recognised right into an illusory declaration. Thirdly, the strategic use of contentious-administrative remedies as a delaying mechanism that has been identified by the workers themselves, constitutes an abuse of the process that instrumentalizes the right to effective judicial protection to the detriment of the structurally weaker party.
In this regard, Picco documents that, in Italy, in the face of the analogous failure of administrative sanctions, the legislator reintroduced criminal sanctions in the field of subcontracting, implicitly recognizing that civil and administrative mechanisms are insufficient to dissuade employers with legal and patrimonial capacity to neutralize them. In addition, Simon adds that the tension between regularization and legal procedures in inspection work generates application inconsistencies that sophisticated employers exploit strategically, deepening the gap between norm and reality.

Perverse asymmetry

Note. It reflects the normalization of non-compliance as a structural practice.
The exponential escalation of cases of wage violations registered by the Regional Directorate of Labor, from 1 case with 15 workers in 2012 to 30 cases with 800 workers between January and September 2015 , should be interpreted not as an indicator of greater inspection effectiveness, but as evidence of the progressive consolidation of an illicit labor economy in the construction sector in Amazonas. From the factual dimension of Reale's three-dimensional theory , this growth reflects the normalization of non-compliance as a structural business practice, not as exceptional conduct.
The central paradox lies in the fact that, despite the volumetric increase in cases, successful sanctions remained marginal. This result is explained in what is documented by Martinelli et al. , where the labour inspectorate, subject to austerity policies and lacking a strategic vision, adopts what is called new regulatory governance, reducing visits to workplaces and focusing on advising employers to the detriment of the coercive function. In contrast, Kaium and Ahsan confirm that when inspection agencies lack local decision-making authority and digital management tools, their capacity for sector-specific intervention is severely limited.
In addition, the fact that the penalties collected benefit the State and not directly the affected workers introduces a perverse asymmetry in the design of the system: labor enforcement does not generate compensation for the victims of non-compliance, dissociating the punitive function from the reparative function that labor law requires for the effective protection of fundamental rights.
4.6. Consortium Structures and Avoidance of Liability
Figure 3. Mechanism of evasion of liability through consortium structure (Art. 445–447, Law).
The widespread use of consortium agreements without solidarity clauses, protected by Articles 445 and 447 of the General Law 26887 of Companies , as a systematic mechanism for avoiding labor obligations constitutes the most sophisticated expression of the elusive legal engineering identified in this study. From the normative dimension of Reale's three-dimensional theory , this phenomenon reveals a pathology of the legal system, where the same norms that regulate the legitimate business organization are instrumentalized to neutralize the labor protection norms, generating a functional antinomy that the legal system does not resolve.
The avoidance mechanism operates on three concurrent levels: first, the constitution of consortia without joint and several liability that fragments the imputation of obligations; second, the registration of assets in the name of third parties that makes it impossible to execute assets; and third, the dissolution of the consortium at the end of the project that extinguishes the legal counterparty before the workers' claims are consolidated. This corporate architecture produces what Syed calls a reversal of the cost-benefit equation of default, where the benefits of avoidance are certain and immediate, while the costs are uncertain, deferred, and in practice sunk from view.
In this regard, Do Prado documents in the Brazilian context that the inspected companies face stricter credit conditions after the interventions, which suggests that mechanisms of anticipated asset allocation such as the proposed guarantee instrument could structurally modify the business rationality before the infringement occurs. Under this premise, Tchawouo reinforces this argument by concluding that the most effective preventive measures are those that directly affect the vital economic interests of the offender, such as disqualification from contracting with the State or exclusion from public tenders.
4.7. Workers' Perspectives on the Proposed Guarantee Mechanism
Table 6. Workers' perspectives on the proposed guarantee mechanism.

Characteristics of the proposed guarantee instrument

Legal justification

A. Essential Attributes of the Mechanism

Irrevocability-Cannot be unilaterally cancelled

It guarantees the subsistence of the title in the event of the dissolution of the consortium

Solidaridad-Banco assumes joint and several responsibility

Overcoming the absence of solidarity in consortium agreements (Art. 447, Law 26887)

Unconditionality – Enforcement without judicial proceedings

Eliminates documented 36-month procedural delay

Immediate enforceability-In the event of violations verified by inspection

Preventive protection: acts before the consummated property damage

Administrative ownership-Issued in favor of the DRT

It endows authority with real coercive power

B. Proposed Implementation Threshold

Projects over 50 UIT (~53,000 USD)

It balances worker protection with the viability of legitimate construction activity

Minor projects: alternative proportional mechanisms

Avoids excessive barriers to entry for small contractors

Note. It shows that unanimous support constitutes an empirical indicator of the structural insufficiency of the current system and social demand for preventive protection.
The unanimous support of 100% of the workers for both the implementation of the guarantee instrument and its issuance in favor of the labor administrative authorities constitutes an empirical fact of exceptional legal relevance, which transcends the mere subjective preference to operate as an indicator of the structural insufficiency of the current system and the social demand for preventive protection mechanisms. From Reale's three-dimensional theory , this pronouncement simultaneously articulates the three dimensions of law: in fact, it recognizes the reality of a failed enforcement system; in the normative, it demands the creation of legal instruments with real enforceability; and in the axiological, it reaffirms the values of human dignity and social justice as the foundation of the proposed reform.
The preference for attributing ownership of the instrument to administrative authorities, rather than to individual workers, reflects an intuitive but legally accurate understanding of the limitations of individual access to justice vis-à-vis employers with superior legal and patrimonial capacity. This design responds to Duguit's principle of continuity of public service: providing the labor authority with an advance enforceable title guarantees the constant application of labor standards regardless of the ability or individual willingness of each worker to litigate.
In this regard, Kaium and Ahsan support this approach by concluding that inspection effectiveness requires giving labor officials real authority to take rapid, sectorally specific action. Martinelli et al. They add that the direct participation of workers in the inspection processes, such as that which this instrument catalyzes by formalizing their expectations in a legal title, is important to facilitate complaints and detect risks. In short, the proposed letter of guarantee operates as a preventive labor compliance mechanism that, by taxing the employer's assets in advance, inverts the illicit rationality documented throughout this study, restoring the coherence between the factual, normative and axiological dimensions of the labor legal system that Reale's three-dimensional theory requires for the effective enforcement of the right.

5. Discussion
The result that 99.3% of workers experienced wage payments below collectively bargained rates demonstrates the systematic and not merely sporadic nature of violations of the fundamental right to fair remuneration . This pattern transcends the individual conduct of the offending employer to evidence a structural fracture in the factual dimension of the labor legal system, in accordance with Reale's three-dimensional theory of law : the norm exists, the values that inspire it are constitutionally recognized, but its social materialization is practically non-existent. Comparable studies in other Latin American countries document similar patterns, with informality rates in the construction sector above 50% in Argentina, Brazil, and Mexico, where the systematically insufficient payment of agreed wages is a widespread practice , which allows us to affirm that the phenomenon identified in the Peruvian Amazon is not a regional anomaly but the local expression of a structural labor pathology of continental.
The prevalence of piecework compensation in 16.9% of respondents, despite the legal right to weekly wage by occupational category, illustrates the employer's strategies for transforming fixed labor costs into variable expenses . This modality constitutes a circumvention of the special labor regime of the construction sector that transfers the productive risk to the worker, undermines the predictability of income, and facilitates remuneration below minimum standards , simultaneously violating ILO Convention 95 on Wage Protection and the constitutional mandate of Article 24 of the Political Constitution of Peru. From the perspective of Bandura's sociocognitive theory, this pattern responds to institutionalized mechanisms of moral disconnection, through which employers perpetuate underpayment while maintaining a self-perception of corporate legitimacy . Negi and Sharma confirm this phenomenon, documenting how organizational cultures that normalize infringement operate as vectors for the systematic reproduction of non-compliance, while Syed demonstrates that when the costs associated with the regulatory violation are lower than the benefits obtained, economic rationalityof the employer is structurally inclined towards the infraction, configuring an institutionalized illicit rationality that no merely reactive system can reverse.
The training deficit found, according to the 66.2% of workers who did not receive any training from the employer, and the existing training was limited to general technical skills , does not constitute an accidental business omission, but a functional mechanism for perpetuating the informational asymmetry that sustains the cycle of labor violations. From the axiological dimension of Reale's three-dimensional theory , human dignity and social justice that defend the supreme values that labor law aspires to realize, require that knowledge of labor rights be a precondition for their effective exercise; its deliberate absence operates as a structural obstacle to access to justice that the State has the obligation to remove.
This result is articulated with the mechanisms of moral disconnection by dehumanization and attribution of blame described by Bandura , by keeping workers in a state of legal ignorance, employers implicitly shift the responsibility for non-compliance to those who do not complain, making invisible the unlawful nature of their conduct. Negi and Sharma identify this same pattern in the Indian construction industry, noting that low registration rates in social welfare systems are partly due to systematic misinformation as an employer evasion strategy, concluding that mandatory safety training and digitization of worker registration are sine qua non conditions to reverse this dynamic. The absence of training in collective bargaining, wage scales and social benefits also compromises the ILO's fourth pillar of decent work, representation and social dialogue, depriving workers of the cognitive tools necessary to assert their rights in spaces of labour consultation, in contravention of what Amartya Sen defines as the minimum institutional conditions for the exercise of decent work as a fundamental right.
Meanwhile, the high rates of use of the available mechanisms with 84.5% of workers submitting requests for labor inspection and 85.5% resorting to administrative conciliation , evidence an active legal awareness and a genuine willingness of workers to exercise their rights through formal channels. However, this massive use contrasts dramatically with its results, revealing that the problem does not lie in the ignorance or passivity of the workers, but in the structural inefficiency of the administrative protection system. As Martinelli et al. The mere use of the mechanisms does not translate into effective protection when the inspection system operates with a structural deficit of resources and reactive and improvised governance, adopting what is called new regulatory governance, which reduces visits to workplaces and prioritizes guidance to employers to the detriment of the coercive function.
The predominance of complaints to the Regional Directorate of Labor (69.0%) compared to decentralized areas (6.3%), marked by accusations of corruption in inspection and conciliation , reflects a selective erosion of institutional legitimacy that concentrates the burden of the system in a single entity, reducing its real operational capacity. This phenomenon embodies the failure to comply with what public service theory calls the principles of continuity, adaptability and equality in protection: when the labour administration does not guarantee these principles, it generates legitimacy deficits that materialise in the 11.3% who chose not to file complaints because they perceived the procedures as a waste of time without significant results . Ramdan confirms that inspection effectiveness requires a coherent articulation between planning, implementation, and reporting; its absence turns procedures into formal rituals with no corrective capacity , while Do Prado documents that even when inspections succeed in formalizing workers, the effects on sustained wage compliance are limited without monitoring and enforcement mechanisms effective patrimonial assets.
Following the analysis with the judicial failure rate of 95.3% among those who filed legal claims, after having previously exhausted the available administrative mechanisms , it configures what from the theory of public service must be qualified as a material and systematic denial of labor justice. The current mechanisms operate sequentially, starting with inspection, administrative conciliation and, finally, judicial litigation, in a process that lasts an average of 3 years , during which workers lack sufficient income to cover their basic needs, compromising the food and priority nature of the wage credit recognized by ILO Convention 95 and Peruvian constitutional jurisprudence.
The central paradox is that even formal victories are illusory, because successful administrative sanctions benefit the state and not directly the affected workers, without providing compensation for wage losses, while favorable court rulings face enforcement difficulties in the absence of attachable assets . This dissociation between legal victory and practical solution explains the perception of failure of 95.3% despite possible formal successes in individual cases, and constitutes the most acute manifestation of the failure to comply with the principle of effectiveness that should guide any protection of fundamental rights. Picco documents that, in Italy, faced with the similar failure of administrative sanctions, the legislator reintroduced criminal sanctions in the matter of subcontracting, implicitly recognizing that civil and administrative mechanisms are insufficient for employers with the legal and patrimonial capacity to neutralize them. Simon adds in this regard that the tension between regularization and legal procedures generates application inconsistencies that sophisticated employers exploit strategically, structurally deepening the gap between norm and reality.
In the case of the exponential escalation of cases registered by the Regional Directorate of Labor with 1 case with 15 workers in 2012 to 30 cases with 800 workers between January and September 2015 , it should be interpreted not as an indicator of greater inspection effectiveness, but as evidence of the progressive consolidation of an illicit labor economy in the construction sector of Amazonas. From the factual dimension of Reale's three-dimensional theory , this growth reflects the normalization of non-compliance as a structural business practice; from the normative dimension, it shows that the increase in complaints has not been accompanied by a proportional sanctioning capacity.
Comparative research underlines the decisive importance of preventive versus merely reactive mechanisms , where the former establish compliance incentives before violations occur, while the latter intervene only after workers file complaints, when the property damage has already been consummated. Current application in the Peruvian construction sector is based almost exclusively on reactive mechanisms, which explains why the increase in the volume of cases does not translate into greater effective protection. Kaium and Ahsan confirm that when inspection agencies lack local decision-making authority and digital management tools, such as the Labour Inspection Management Application (LIMA), their capacity for sector-specific intervention is severely limited, producing negative or no correlations between the number of inspections and effective compliance with labour standards. The additional fact that the penalties collected benefit the State and not the affected workers introduces a perverse asymmetry in the design of the system, dissociating the punitive function from the reparative function that labor law requires for the comprehensive protection of fundamental rights.
The widespread use of consortium agreements without solidarity clauses, protected by Articles 445 and 447 of Law 26887, as a systematic mechanism for avoiding labor obligations constitutes the most sophisticated expression of what this study calls evasive legal engineering . From the normative dimension of Reale's three-dimensional theory , this phenomenon reveals a pathology of the legal system, where the same norms that legitimately regulate the business organization are instrumentalized to neutralize the labor protection norms, generating a functional antinomy that the legal system does not resolve. While consortia serve legitimate business purposes by pooling resources for large projects, sharing risk, and combining specialized capabilities, their use to evade labor obligations perverts this legal form, transforming it into a shield against liability.
Employers' behavior patterns align unequivocally with Bandura's theory of moral disconnection , which justify wage violations by claims of economic necessity (moral justification), characterize underpay as temporary adjustments (euphemistic labeling), attribute liability to subcontractors or market conditions (liability shifting), and employ corporate structures that spread accountability. Latin American labor law research increasingly recognizes the need to apply corporate veiling doctrines in labor contexts, allowing courts to ignore formal separations when they are used to evade labor obligations . Syed demonstrates that when the costs of avoidance are lower than the benefits obtained, economic rationality is consolidated as the driver of non-compliance, and that only mechanisms that affect the employer's vital patrimonial interests in advance, such as disqualification from contracting with the State or exclusion from tenders, have sufficient deterrent capacity, a conclusion reinforced by Tchawouo , which advocates administrative sanctions that have a direct impact on the economic viability of the offender as instruments of labor compliance with greater preventive and corrective effectiveness.
The unanimous support of 100% of the workers for both the implementation of the guarantee instrument and its issuance in favor of the labor administrative authorities constitutes an empirical fact of exceptional legal relevance that transcends the mere subjective preference to operate as an indicator of the structural insufficiency of the current system and the social demand for preventive protection mechanisms. From Reale's three-dimensional theory , this pronouncement simultaneously articulates the three dimensions of law: in fact, it recognizes the reality of a failed enforcement system; in the normative, it demands legal instruments with real and anticipated enforceability; and in the axiological, it reaffirms the values of human dignity and social justice as the foundation of the proposed reform.
The proposed letter of guarantee mechanism builds on successful models in other regulated sectors where government procurement requires fidelity guarantees prior to contract performance; utility concessions require continuity guarantees; inspection centres must provide substantial guarantees of between $50,000 and $100,000; and renewable energy generators provide guarantees covering obligations until the start of operations commercial. These precedents demonstrate that requiring guarantees from regulated entities is a fully accepted regulatory practice, whose essential characteristics of irrevocability, solidarity of the issuing bank, unconditionality, immediate enforceability and issuance in favor of the regulatory authority, make it an ideal instrument for the preventive protection of salary credit .
Finally, the preference for attributing ownership of the instrument to the administrative authorities, rather than to individual workers, reflects a legally accurate understanding of the limitations of individual access to justice vis-à-vis employers with superior legal and patrimonial capacity. This design responds to Duguit's principle of continuity of public service and is in line with what has been documented by Kaium and Ahsan , who conclude that inspection effectiveness requires granting labor officials real authority to adopt rapid and sectorally specific measures. Martinelli et al. They add that the direct participation of workers in the inspection processes is crucial to facilitate complaints and detect risks, a condition that the guarantee instrument catalyzes by formalizing their expectations in an enforceable legal title. In short, the proposed letter of guarantee operates as a preventive labor compliance mechanism that, by taxing the employer's assets in advance, inverts the illicit rationality documented throughout this study, transforms the application of a reactive punishment into a preventive protection and restores the coherence between the factual, normative and axiological dimensions of the labor legal system that Reale's three-dimensional theory required for the effective enforcement of the right to decent work.
6. Conclusions
This research demonstrates a systematic violation of the labour rights of construction workers in the Amazonas region, Peru, with 99.3% of workers suffering wage payments below collectively bargained rates. Despite the high use of administrative complaints (84.5% submit inspection requests, 85.5% seek conciliation), current enforcement mechanisms are insufficient, with 95.3% of legal complaints perceived as unsuccessful. Average three-year procedures, the employer's use of consortium structures for the decentralization of liabilities, and the absence of executable assets create conditions in which workers rarely recover wages owed despite formal legal victories.
The proposed letter of guarantee mechanism addresses these shortcomings by establishing defensive protection. Requiring construction employers to provide irrevocable, solidary, and unconditional bank guarantees to labor authorities for projects exceeding 50 UIT would allow for the immediate payment of wages in the event of verified violations, regardless of employer cooperation or availability of assets. This approach aligns with established regulatory practices in the public procurement, postal services, vehicle inspection, and renewable energy sectors, where guarantees successfully ensure regulatory compliance.
The results of the research support four important conclusions. First, labor rights violations in the construction sector in the Amazon region are systematic and not sporadic phenomena, reflecting structural deficiencies in implementation rather than individual failures by employers. Second, the current mechanisms of sequential application (administrative inspection, conciliation and judicial litigation) are ineffective in guaranteeing the payment of salaries, requiring average processes of 3 years without guaranteeing practical remedies. Third, employer strategies, including consortium structures without solidarity agreements, the registration of assets in the name of third parties, and strategic litigation, effectively immunize employers from accountability. Fourth, workers universally support the implementation of guarantee mechanisms issued to labor authorities, recognizing that strengthening enforcement administrative capacities better protects their rights than relying on individual legal actions.
From theoretical perspectives, the research validates the three-dimensional theory of the usefulness of law to analyze labor regulation. The factual dimension manifests itself in documented patterns of violations, the normative dimension encompasses constitutional and conventional protections, and the axiological dimension refers to decent work and the values of human dignity. Effective regulation requires coherence in these dimensions, something that current enforcement mechanisms do not achieve. The proposed guarantee mechanism would strengthen policy-factual coherence by creating enforceable financial instruments to support legal obligations.
The policy implications emphasize the need for preventive rather than exclusively reactive enforcement mechanisms. The Ministry of Labor should issue supreme decrees requiring bank letters of credit for construction projects in excess of 50 UIT, specifying guarantee amounts, conditions of execution, and administrative procedures. Such regulations would align with existing legal frameworks, including Article 118 of the Constitution (supreme power to regulate decrees), ILO Convention 95 on wage protection, and comparative regulatory precedents for other sectors.
Implementation requires inter-institutional coordination between labor authorities, the banking superintendence, and financial institutions. Clear regulatory frameworks should specify banks' obligations and liabilities while providing standardized formats of guarantees. Training programs should prepare labor inspectors to verify the provision of guarantees, document violations that justify their application, and administer guarantee funds for the payment of workers.
The research contributes to research in labour law by documenting failures in the mechanisms for implementing special labour regimes and proposing innovative financial instruments for labour protection. Although focused on the Peruvian construction sector, the findings have broader relevance for developing countries, where resources for labour inspection remain limited, informal employment predominates, and workers lack effective access to justice. The guarantee mechanism model offers replicable approaches to strengthen the protection of labor rights in vulnerable sectors.
Future implementation should proceed through pilot programs in selected provinces, allowing for evaluation of effectiveness and improvement of procedures prior to national expansion. Monitoring frameworks should record compliance rates, ensure execution frequency, worker satisfaction, and impact on the construction industry. Regular evaluation would support evidence-based policy adjustments, ensuring that mechanisms effectively protect workers and avoid unintended consequences.
In general conclusion, addressing systematic violations of labor rights in the Peruvian construction sector requires moving beyond reactive enforcement to preventive protection mechanisms. Bank letters of credit issued to labour authorities represent viable and legally supported instruments to guarantee the payment of wages regardless of the employer's cooperation. Combined with increased inspection capacity, improved administrative procedures, and increased union oversight, these mechanisms can promote decent work for construction workers, while promoting responsible practices for employers. The urgency of protecting workers' fundamental rights – rights that have a nutritional character essential to human dignity – requires immediate political action to implement these protective measures.
