Draft Labour Protection Bill 2025

Overview

The Draft Labour Protection Bill (Second Draft Bill) 2025 represents a significant legislative initiative by the Thai government to modernize and strengthen the framework for worker protection, with a particular emphasis on promoting pay equity and eliminating wage discrimination. This comprehensive bill aims to consolidate various existing labour regulations, introduce new provisions aligned with international labour standards, and address contemporary challenges in the Thai labour market, such as persistent gender pay gaps and the need for greater transparency. The primary purpose of this draft legislation is to ensure fair treatment and equal opportunities for all employees, irrespective of gender, age, religion, disability, or other protected characteristics, by establishing clear principles for remuneration and working conditions. It seeks to create a more transparent and equitable wage system across all sectors of the economy, fostering a more just, productive, and harmonious workforce that can contribute effectively to national development.

Historically, Thailand's labour laws have evolved incrementally, often in response to specific industrial needs or international pressures. While existing legislation, such as the Labour Protection Act B.E. 2541 (1998), contains general provisions against unfair labour practices and some basic protections, it has been recognized that more explicit and robust mechanisms are needed to tackle systemic pay disparities and ensure true equality in remuneration. This Second Draft Bill builds upon earlier proposals and extensive consultations with social partners, including employer organizations, trade unions, and civil society groups, reflecting a concerted effort to develop a consensus-driven approach to labour reform. The impetus for this draft also stems from Thailand's commitments under various international conventions, particularly those related to equal remuneration for work of equal value, underscoring a global trend towards enhanced pay equity legislation and a desire to improve Thailand's standing in international labour rights indices.

Key innovations introduced by the Draft Labour Protection Bill 2025 include explicit and detailed definitions of 'work of equal value' and 'equal remuneration,' mandatory pay transparency requirements for certain employers (such as salary range disclosure in job advertisements), and significantly enhanced enforcement powers for labour inspectors. The bill proposes a proactive approach to identifying and rectifying pay gaps, moving beyond reactive complaint-based systems to require regular reporting and audits. It also outlines specific, streamlined procedures for employees to seek redress for wage discrimination and introduces a comprehensive framework for regular monitoring and evaluation of pay practices across the country. This legislative effort is crucial for Thailand's economic development, as it aims to improve worker welfare, boost productivity through fairer compensation, and enhance the country's reputation as a responsible participant in the global economy. The Ministry of Labour is the primary proponent of this bill, having spearheaded its development through various stages of review and public consultation, demonstrating a strong governmental commitment to these reforms.

Definitions

The Draft Labour Protection Bill (Second Draft Bill) 2025 introduces several critical definitions to clarify its scope and application, particularly concerning pay equity. "Equal Remuneration" is defined as the payment of wages or salary without discrimination based on gender, age, religion, disability, or any other protected characteristic, for work that is considered to be of "equal value." This definition extends beyond basic salary to encompass all forms of remuneration, including allowances (e.g., housing, transport), benefits (e.g., health insurance, pension contributions), bonuses (e.g., performance, year-end), and any other monetary or non-monetary compensation provided by an employer in connection with employment. The bill emphasizes that the principle of equal remuneration applies not only to identical jobs but also to jobs that, while different in nature, are objectively assessed as having comparable worth based on a set of neutral criteria. This broad interpretation is crucial for addressing both direct and indirect forms of pay discrimination, ensuring that the entire compensation package is free from bias.

The concept of "Work of Equal Value" is central to the bill's pay equity provisions and is defined as work that, when objectively assessed, requires comparable levels of skill, effort, responsibility, and is performed under similar working conditions, even if the job titles or specific tasks may differ. The bill provides guidance on the criteria to be used for such objective assessment, which may include educational qualifications, professional training, years of experience, mental and physical demands of the job, level of decision-making authority, supervisory responsibilities, and the nature of the working environment (e.g., hazardous conditions, irregular hours). This definition aims to prevent employers from circumventing equal pay obligations by creating slightly different job descriptions or titles for roles that are fundamentally equivalent in value. The objective assessment criteria are intended to be applied in a gender-neutral and bias-free manner, ensuring that traditional biases in job valuation, which often undervalue work predominantly performed by women, are minimized and systematically eliminated.

Furthermore, the bill defines "Wage" and "Remuneration" broadly to cover all forms of payment made by an employer to an employee for work performed. "Wage" specifically refers to money paid by an employer to an employee in return for work done during normal working hours, whether calculated on a time or piece-rate basis, and includes payments for holidays, sick leave, and annual leave, as stipulated in the employment contract or collective agreement. "Remuneration" is a more encompassing term, covering not only wages but also overtime pay, holiday pay, severance pay, and any other benefits or allowances that are part of the employment contract or customary practice, such as housing allowances, travel expenses, or performance-based bonuses. The distinction ensures that the equal pay principle applies to the entire compensation package, preventing employers from offering equal base salaries but unequal benefits or bonuses based on protected characteristics. These precise and comprehensive definitions are fundamental to the effective implementation and enforcement of the bill's pay equity provisions, providing much-needed clarity for both employers and employees.

Covered Employers

The Draft Labour Protection Bill (Second Draft Bill) 2025 establishes clear criteria for covered employers, ensuring that its pay equity and labour protection provisions apply broadly across the Thai economy while also considering the practicalities for smaller enterprises. The bill generally applies to all employers operating within Thailand, regardless of their legal form (e.g., sole proprietorships, partnerships, limited companies, public companies, state enterprises, or non-profit organizations). This universal application ensures that the fundamental principles of equal remuneration and non-discrimination are upheld across the entire workforce. However, specific provisions, particularly those related to mandatory pay gap reporting and comprehensive pay equity audits, are phased in based on employer size. Employers with 50 or more regular employees are subject to the full scope of the pay transparency and reporting obligations. This threshold is chosen to balance the administrative burden on small businesses with the need to capture a significant portion of the workforce where pay disparities are more likely to occur and have a broader societal impact, ensuring that the majority of formal sector employees are covered by these enhanced protections.

For employers with fewer than 50 employees, the bill mandates strict adherence to the fundamental principles of equal remuneration for work of equal value and explicitly prohibits wage discrimination based on protected characteristics. While these smaller entities are not immediately required to undertake extensive pay gap reporting or external audits, they are still subject to inspections and investigations by labour authorities if complaints of discrimination are raised. The Ministry of Labour is tasked with developing simplified guidelines, educational materials, and accessible resources to assist small and medium-sized enterprises (SMEs) in understanding and complying with the basic tenets of the bill, ensuring that compliance is achievable without undue burden. The intent is to foster a culture of pay equity across all business sizes, gradually expanding the more stringent reporting requirements as businesses grow and administrative capacities improve. The bill also clarifies that temporary, part-time, or contract workers, if they perform work of equal value to permanent employees, must receive equal remuneration, preventing the use of precarious employment arrangements to circumvent pay equity obligations and ensuring fair treatment for all types of workers.

Certain limited exemptions from specific reporting requirements may apply to very small businesses (e.g., those with fewer than 10 employees), though the core anti-discrimination principles remain universally applicable and enforceable. The bill outlines a clear phase-in period for the more complex compliance obligations to allow businesses sufficient time for adaptation. For instance, mandatory pay gap reporting for employers with 50-200 employees will commence 18 months after the bill's enactment, while those with over 200 employees will be required to comply within 12 months. This staggered approach aims to provide businesses with sufficient time to adapt their internal systems, conduct necessary data collection, implement new HR policies, and train their staff. The bill also explicitly specifies that public sector entities, including all government agencies, ministries, departments, and state-owned enterprises, are fully covered by all provisions, setting a leading precedent for fair employment practices across the nation. This comprehensive coverage ensures that the vast majority of the Thai workforce benefits from enhanced labour protections and robust pay equity measures.

Employee Rights

The Draft Labour Protection Bill (Second Draft Bill) 2025 significantly enhances employee rights concerning pay equity and non-discrimination in the workplace, establishing a robust framework for fair treatment. Central to these rights is the explicit entitlement to "equal remuneration for work of equal value," regardless of gender, age, religion, disability, national origin, or any other protected characteristic. Employees have the fundamental right to request information from their employer regarding the criteria used for determining pay, promotion, and career progression, provided such requests are reasonable and do not infringe upon the privacy of other individual employees. This right to information is designed to empower employees to assess whether they are being paid fairly in comparison to colleagues performing comparable work, thereby enabling them to identify and challenge potential disparities. The bill outlines a clear procedure for such requests, requiring employers to respond within 30 days with relevant, anonymized data, aggregated statistics, or a clear, objective explanation of their pay structure and decision-making processes. This transparency mechanism is a cornerstone of the bill's proactive approach to achieving pay equity.

Furthermore, the bill grants employees the unequivocal right to discuss their wages, salary, and working conditions with colleagues, trade union representatives, or external advisors without any fear of retaliation or adverse consequences. Any contractual clause, employment agreement, or employer policy that prohibits employees from discussing their pay or seeking information about compensation is deemed null and void under this legislation, rendering such clauses unenforceable. This provision aims to dismantle historical barriers to identifying and challenging pay disparities, as open communication among employees is often critical for uncovering potential discrimination and fostering collective action. Employees also have the right to file a complaint with the Labour Protection and Welfare Department (LPWD) if they believe they have been subjected to wage discrimination, denied equal remuneration, or retaliated against for exercising their rights. The bill ensures that employees who exercise these rights are protected from any adverse employment action, such as dismissal, demotion, harassment, or reduction in benefits, establishing robust anti-retaliation provisions. Employers found to have retaliated against an employee will face severe penalties, including substantial fines and potential criminal charges for individuals responsible.

In cases where an employee suspects pay discrimination, they have the right to initiate an internal review process with their employer before escalating the matter to external authorities. The bill strongly encourages employers to establish clear, accessible, and fair internal grievance mechanisms for addressing pay equity concerns promptly and effectively. If the internal process does not resolve the issue to the employee's satisfaction, or if the employer fails to respond adequately, employees can then file a formal complaint with the designated government agency, the LPWD, which will initiate a thorough investigation. The burden of proof in such cases is partially shifted to the employer, requiring them to demonstrate that any pay differential is based on objective, non-discriminatory factors (e.g., seniority, documented merit, specific qualifications, or verifiable market rates for specialized skills) rather than protected characteristics. This shift aims to facilitate the challenging of discriminatory practices, recognizing the inherent power imbalance between employers and employees. The bill also provides for access to legal aid, advisory services, and support organizations for employees pursuing pay equity claims, ensuring that justice is accessible to all workers, regardless of their financial means or legal expertise.

Pay Transparency Requirements

The Draft Labour Protection Bill (Second Draft Bill) 2025 introduces significant pay transparency requirements aimed at fostering a more equitable, accountable, and fair wage environment across the Thai labour market. For employers with 50 or more employees, the bill mandates the disclosure of salary ranges in all job advertisements and postings, both internal and external. This requirement applies to all positions, from entry-level roles to senior management, and aims to provide applicants with clear and realistic expectations regarding potential earnings before they invest time and effort in the application process. The disclosed salary range must reflect the actual compensation structure for the role, including the base salary and any guaranteed bonuses, allowances, or commissions that are an integral part of the remuneration package. The purpose of this provision is to reduce information asymmetry between employers and job seekers, enabling more informed career decisions and helping to mitigate discriminatory pay offers that often occur during the hiring process due to lack of transparency. Non-compliance with this requirement will result in administrative fines for the employer, escalating with repeated offenses.

Beyond job postings, employers with 100 or more employees are required to publish their pay scales or salary bands for various job categories and grades within their organization. This information must be made easily accessible to all employees, either through a secure internal company portal, a dedicated HR platform, or by posting it in a prominent and easily visible location within the workplace, such as a staff notice board. The published pay scales should clearly indicate the minimum and maximum remuneration for each job grade or position, along with the objective, non-discriminatory criteria used for progression within those bands (e.g., documented performance evaluations, additional certifications, years of relevant experience, or acquisition of new skills). This internal transparency is intended to allow employees to understand how their pay is determined, how they can advance, and to identify potential discrepancies in comparison to colleagues in similar roles, fostering a sense of fairness. The bill specifies that this information must be updated annually, by January 31st of each year, reflecting any changes in the company's compensation structure, job classifications, or pay policies. The Ministry of Labour will provide templates and detailed guidelines to assist employers in fulfilling this obligation consistently.

Furthermore, the bill introduces a requirement for employers with 200 or more employees to provide an individualized pay statement to each employee at least once a year, typically by the end of the first quarter. This statement must detail their current base salary, any bonuses, allowances, and the specific objective criteria that influenced their remuneration during the preceding year. Crucially, this statement must also include information on how the employee's pay compares to the average pay for employees in similar roles or job grades within the company, presented in an anonymized and aggregated format to protect individual privacy while providing meaningful comparative data. This level of personalized transparency is designed to empower employees with specific data relevant to their own compensation, enabling them to identify and question any perceived pay gaps or inconsistencies. The bill allows for the provision of these statements electronically, provided employees have easy and secure access to digital platforms and the option to request a physical copy. These comprehensive pay transparency measures are expected to drive greater accountability from employers and facilitate the proactive identification and elimination of systemic pay discrimination across the Thai workforce, leading to more equitable outcomes.

Reporting & Audit Obligations

The Draft Labour Protection Bill (Second Draft Bill) 2025 imposes significant reporting and audit obligations on employers to ensure robust compliance with pay equity principles and to facilitate ongoing monitoring of wage disparities. Employers with 50 or more employees are mandated to submit an annual Pay Equity Report to the Labour Protection and Welfare Department (LPWD). This comprehensive report, due by March 31st of each year, must include aggregated data on remuneration broken down by gender, job category, pay grade, and other protected characteristics where relevant and feasible. It requires employers to analyze and report on any identified pay gaps within their organization, providing clear, objective explanations for these disparities based on non-discriminatory factors such as seniority, qualifications, performance, or market rates for specific skills. The report must also outline the specific measures the employer is currently taking or plans to take to address and reduce any unjustified pay gaps, including timelines and measurable objectives. The Ministry of Labour will issue detailed templates, data collection methodologies, and guidelines for these reports, ensuring consistency and comparability across different organizations and sectors. Failure to submit the report, or submission of incomplete or inaccurate data, will incur administrative penalties.

For employers with 200 or more employees, the bill introduces an additional, more stringent requirement for a mandatory external pay equity audit every three years. These audits must be conducted by independent, certified auditors who are approved and registered with the Ministry of Labour, possessing expertise in labour law, statistics, and human resources. The audit methodology will involve a detailed, systematic analysis of the employer's entire compensation practices, job evaluation systems, recruitment and promotion processes, and pay structures to identify any direct or indirect pay discrimination. The auditor will assess whether jobs of equal value are receiving equal remuneration and will scrutinize the objective justifications provided by the employer for any pay differentials, ensuring they are legitimate and non-discriminatory. The comprehensive audit report, including detailed findings, statistical analysis, and concrete recommendations for corrective actions, must be submitted to both the employer and the Labour Protection and Welfare Department. Employers are then legally required to develop and implement a time-bound action plan to address any identified issues within a specified timeframe, typically 12-18 months, and report on their progress in subsequent annual Pay Equity Reports, demonstrating continuous improvement.

The bill also empowers the Labour Protection and Welfare Department to conduct its own unannounced inspections and internal audits of any employer, regardless of size, if there are reasonable grounds to suspect non-compliance, if a pattern of complaints emerges, or in response to specific employee complaints. These departmental audits will involve a thorough review of payroll records, employment contracts, job descriptions, performance appraisal documents, and all relevant HR policies and procedures. Labour inspectors are also authorized to interview employees and management to gather comprehensive information. The frequency of these departmental audits will be determined by a risk-based approach, prioritizing sectors or companies with a history of complaints, identified systemic issues, or significant pay gaps reported in aggregated data. The data collected through annual reports and mandatory external audits will be used by the Ministry of Labour to monitor national pay equity trends, identify sectors or industries requiring specific policy intervention, and publish aggregated, anonymized statistics to raise public awareness and inform policy development. This multi-layered approach to reporting and auditing is designed to create a robust system of accountability and continuous improvement in pay equity practices across Thailand, fostering a fairer labour market.

Governance & Enforcement Bodies

The primary governance and enforcement body for the Draft Labour Protection Bill (Second Draft Bill) 2025 is the **Labour Protection and Welfare Department (LPWD)**, operating under the Ministry of Labour. The LPWD is vested with extensive powers and responsibilities to oversee the implementation of the bill's provisions, particularly those related to pay equity and non-discrimination. Its core roles include receiving, investigating, and resolving complaints of wage discrimination, conducting proactive inspections and comprehensive audits of workplaces, issuing compliance orders to rectify non-compliant practices, and imposing administrative penalties for violations. The LPWD is also responsible for developing and disseminating clear guidelines, standardized templates, and comprehensive educational materials to assist both employers and employees in understanding their respective rights and obligations under the new law. Regional and provincial offices of the LPWD will serve as the first point of contact for most complaints and inquiries, ensuring accessibility for workers across the country. The Department will establish a dedicated unit or significantly expand an existing one to specialize in pay equity matters, staffed by highly trained labour inspectors, statisticians, and legal experts capable of conducting complex pay analyses and investigations.

In addition to the LPWD, the bill establishes a new advisory body, the **National Pay Equity Committee (NPEC)**, which will play a crucial role in policy development, strategic oversight, and public advocacy. The NPEC will be composed of a diverse group of representatives from the Ministry of Labour, prominent employer organizations, leading trade unions, academic experts in labour economics, statistics, and law, and civil society groups advocating for gender equality and workers' rights. Its broad mandate includes advising the Minister of Labour on policy matters related to pay equity, reviewing the overall effectiveness of the bill's implementation, recommending amendments to the law or its accompanying regulations, and promoting best practices among employers through awareness campaigns and recognition programs. The NPEC will also be responsible for analyzing the aggregated data from employer reports and audits to identify systemic issues, emerging trends, and propose national strategies for reducing the overall pay gap in Thailand. This multi-stakeholder committee aims to ensure that the implementation of the bill is informed by diverse perspectives, remains responsive to evolving labour market dynamics, and fosters a collaborative approach to achieving pay equity.

The bill also outlines the crucial role of the **Labour Court** system in adjudicating disputes that cannot be resolved through administrative channels or where parties seek higher levels of redress. Employees who are dissatisfied with the LPWD's decision, or who seek higher compensation for damages resulting from severe or persistent wage discrimination, can file a case with the Labour Court. The Labour Court will have specialized jurisdiction over claims related to equal remuneration, unfair dismissal due to pay equity complaints, and other violations of the bill's provisions, ensuring expert judicial review. The bill streamlines the process for bringing such cases, aiming for timely and efficient resolution. Furthermore, the **Office of the Attorney General** will be responsible for prosecuting criminal offenses arising from severe or repeated violations of the bill, particularly those involving intentional discrimination, systemic non-compliance, or retaliation against employees for exercising their rights. These interconnected bodies form a comprehensive governance and enforcement framework designed to ensure robust protection of pay equity rights and effective redress for victims of discrimination, thereby upholding the rule of law in the workplace.

Monitoring & Evaluation

The Draft Labour Protection Bill (Second Draft Bill) 2025 establishes a robust and multi-faceted framework for the continuous monitoring and evaluation of its pay equity provisions, ensuring ongoing oversight, effectiveness, and adaptability. The Labour Protection and Welfare Department (LPWD) is mandated to conduct regular, systematic inspections of workplaces to verify compliance with the bill's requirements. These inspections can be routine, scheduled based on a risk assessment (e.g., targeting industries with known historical pay disparities, sectors with a high proportion of female workers, or companies with a history of labour violations), or triggered by specific complaints. During inspections, labour inspectors are authorized to examine a wide range of documents, including payroll records, employment contracts, job descriptions, performance appraisal documents, and any other relevant HR policies and procedures. They can also interview employees and management confidentially to gather comprehensive information regarding pay practices and job valuation methods. The bill specifies that inspectors must undergo specialized training in pay equity principles, objective job evaluation methodologies, and anti-discrimination law to effectively identify and address potential discrimination. Findings from inspections will lead to either compliance orders, recommendations for improvement, or initiation of formal enforcement actions, depending on the severity of the non-compliance.

The investigation of complaints related to pay discrimination is a critical component of the monitoring process, providing a direct channel for employees to seek redress. When an employee files a complaint, the LPWD is required to conduct a thorough, impartial, and timely investigation within a specified timeframe, typically 60 days from the date of receipt. This involves gathering comprehensive evidence from both the complainant and the employer, conducting interviews, reviewing documentation, and mediating disputes where appropriate. The bill outlines clear procedural steps for investigations, including the right for both parties to present their case, submit evidence, and be heard. If the investigation concludes that pay discrimination has occurred, the LPWD will issue a legally binding order requiring the employer to rectify the situation. This may include adjusting the employee's pay retroactively, compensating for any lost earnings, and implementing systemic changes to prevent future discrimination. The LPWD will also actively monitor the employer's compliance with such orders to ensure that corrective actions are effectively and sustainably implemented, providing follow-up support and verification.

Beyond individual complaints and inspections, the bill mandates a broader, systemic evaluation of its impact on national pay equity trends. The National Pay Equity Committee (NPEC), in conjunction with the Ministry of Labour, will be responsible for periodically reviewing the aggregated and anonymized data derived from annual employer reports and mandatory external audits. This comprehensive data will be used to assess the overall effectiveness of the legislation in reducing the gender pay gap and other forms of wage discrimination across different sectors, regions, and demographic groups. Evaluation criteria will include changes in reported pay gaps over time, the number of complaints received and successfully resolved, the types and frequency of enforcement actions taken, and qualitative feedback from employers, employees, and trade unions regarding the clarity, practicality, and impact of the law. A comprehensive review of the bill's implementation and overall impact is specifically scheduled to be conducted five years after its enactment, with detailed findings and recommendations for potential legislative amendments or policy adjustments to be submitted to the Cabinet and Parliament. This continuous monitoring and evaluation cycle ensures that the law remains relevant, effective, and responsive to evolving societal and economic conditions in achieving its objectives of a fairer and more equitable labour market.

Enforcement & Penalties

The Draft Labour Protection Bill (Second Draft Bill) 2025 establishes a clear, graduated, and progressive system of enforcement and penalties designed to ensure robust compliance with its pay equity and labour protection provisions. For initial administrative violations, such as the failure to submit annual pay equity reports by the deadline, the omission of required salary ranges in job postings, or the failure to publish internal pay scales, employers may face administrative fines ranging from 50,000 Baht to 200,000 Baht per instance of non-compliance. These fines are designed to serve as a significant deterrent and to encourage prompt rectification of procedural shortcomings. The Labour Protection and Welfare Department (LPWD) has the explicit authority to issue formal compliance orders, legally requiring employers to rectify non-compliant practices within a specified and reasonable period. Failure to comply with such orders can lead to escalated fines, potentially doubling the initial penalty, and may trigger more intensive monitoring, mandatory external audits at the employer's expense, or even public naming and shaming. The bill emphasizes a graduated approach, aiming first for voluntary compliance and corrective action before resorting to more severe sanctions.

More serious violations, particularly those involving direct wage discrimination, systemic failure to provide equal remuneration for work of equal value, or intentional circumvention of the law, carry substantially higher penalties. Employers found guilty of such discrimination may face fines ranging from 300,000 Baht to 1,000,000 Baht for each affected employee, reflecting the severity of the harm caused. In cases where the discrimination is deemed intentional, malicious, or systemic, or where it involves retaliation against an employee for exercising their rights under the bill (e.g., discussing wages, filing a complaint), criminal liability may be imposed. Individuals directly responsible for such actions, including company directors, human resources managers, or other senior management, could face imprisonment for up to one year, in addition to significant personal fines ranging from 100,000 Baht to 500,000 Baht. The bill also explicitly provides for victims of discrimination to seek comprehensive compensation for lost wages, emotional distress, and other damages through the Labour Court, with the possibility of punitive damages in egregious cases to deter future misconduct. The court may order reinstatement, compensation in lieu of reinstatement, or other equitable remedies, ensuring comprehensive redress for affected workers.

The appeals process for penalties and compliance orders is clearly defined to ensure due process and fairness. Employers have the right to appeal administrative decisions of the LPWD to a higher administrative body within 30 days of receiving the decision. If still dissatisfied with the administrative appeal outcome, they can further appeal to the Labour Court for judicial review. Similarly, employees can appeal LPWD decisions regarding their complaints to the Labour Court if they believe the resolution was inadequate or incorrect. The bill aims to ensure fair hearings and transparent processes for all parties involved. Repeat offenders or employers who consistently fail to comply with the bill's provisions, despite warnings, penalties, and compliance orders, may face increasingly severe sanctions. These could include public naming and shaming on the Ministry of Labour's website, temporary suspension of business licenses, or even permanent revocation of operating licenses in extreme and persistent cases of non-compliance. The Ministry of Labour will maintain a public registry of non-compliant employers to enhance transparency and accountability across the labour market. This comprehensive enforcement regime is designed to ensure that the principles of pay equity are not merely aspirational but are rigorously upheld across the Thai labour market, fostering a culture of fairness and respect for workers' rights.

Relationship to Other Laws

The Draft Labour Protection Bill (Second Draft Bill) 2025 is meticulously designed to complement, strengthen, and integrate with existing labour legislation in Thailand, particularly the foundational Labour Protection Act B.E. 2541 (1998). While the Labour Protection Act provides a general framework for working conditions, minimum wages, welfare, and basic employee rights, the new bill introduces more specific, detailed, and robust provisions concerning pay equity and non-discrimination. The new bill will take precedence in matters where its provisions are more specific or offer greater protection to employees regarding equal remuneration for work of equal value. For instance, while the existing Act prohibits general unfair labour practices, the Draft Bill explicitly defines wage discrimination, establishes objective criteria for assessing work value, and mandates detailed mechanisms for its prevention, identification, and redress. Any provisions in the Labour Protection Act or other related decrees that are inconsistent with the principles of equal pay and non-discrimination as defined in the 2025 Bill will be deemed superseded or interpreted in harmony with the new, more protective legislation, ensuring a coherent and progressive legal framework.

The bill also interacts significantly with other relevant Thai laws that address discrimination, such as the Persons with Disabilities Empowerment Act B.E. 2550 (2007) and the Gender Equality Act B.E. 2558 (2015). The Gender Equality Act already prohibits gender-based discrimination in various spheres, including employment, but often lacks specific mechanisms for addressing pay disparities. The Draft Labour Protection Bill 2025 specifically operationalizes this principle within the critical context of remuneration, providing concrete tools, reporting obligations, and enforcement procedures for addressing gender pay gaps directly. It ensures that the general anti-discrimination principles of the Gender Equality Act are translated into actionable requirements for employers regarding wage practices, moving beyond mere prohibition to proactive measures. Similarly, the bill reinforces the rights of persons with disabilities by explicitly including disability as a protected characteristic against wage discrimination, aligning with and strengthening the protections offered by the Persons with Disabilities Empowerment Act, ensuring that all forms of discrimination in pay are comprehensively covered and addressed.

Furthermore, the bill's provisions on data collection, reporting, and privacy will need to be carefully harmonized with Thailand's Personal Data Protection Act B.E. 2562 (2019) (PDPA). While the bill mandates the collection and reporting of aggregated pay data to identify disparities, it also places a strong emphasis on the importance of protecting individual employee privacy. The Ministry of Labour will issue specific regulations or detailed guidelines to ensure that employers comply with both the pay transparency and reporting requirements of the Labour Protection Bill and the stringent data protection principles of the PDPA, particularly concerning the anonymization of individual data, secure handling of sensitive information, and obtaining consent where necessary. The bill also considers its relationship with collective bargaining agreements. While it sets minimum statutory standards for pay equity and non-discrimination, it does not preclude trade unions and employers from negotiating more favorable terms and conditions through collective agreements, provided such agreements do not undermine or diminish the fundamental rights and protections established by the bill. The overarching goal is to create a comprehensive, integrated, and mutually reinforcing legal landscape that effectively promotes fairness, equality, and decent work in the Thai workplace.

International Context

The Draft Labour Protection Bill (Second Draft Bill) 2025 significantly aligns Thailand's labour legislation more closely with key international labour standards, particularly those established by the International Labour Organization (ILO). The bill's core principle of "equal remuneration for work of equal value" directly reflects ILO Convention No. 100 on Equal Remuneration (1951), which Thailand ratified in 1999. By providing explicit definitions for "equal remuneration" and "work of equal value," establishing objective job evaluation criteria, and introducing robust enforcement mechanisms, the bill aims to give practical and enforceable effect to the commitments made under C100, moving beyond mere ratification to active implementation. Furthermore, the bill's broader anti-discrimination provisions, covering various protected characteristics such as gender, age, religion, and disability, resonate strongly with ILO Convention No. 111 on Discrimination (Employment and Occupation) (1958), which Thailand also ratified. The emphasis on pay transparency, mandatory reporting, and external auditing mirrors recommendations from the ILO for effective implementation of equal pay principles, advocating for proactive measures to identify and rectify systemic disparities rather than solely relying on reactive complaint-based systems. This legislative effort demonstrates Thailand's commitment to fulfilling its international obligations and promoting decent work principles globally.

Beyond ILO conventions, the Draft Labour Protection Bill 2025 reflects a growing global trend towards enhanced pay equity legislation and greater transparency in compensation practices. Many jurisdictions, particularly within the European Union, have adopted or are in the process of adopting comprehensive directives and national laws that mandate pay transparency, gender pay gap reporting, and pay equity audits. For example, the EU Pay Transparency Directive (Directive (EU) 2023/970) sets a comprehensive framework for member states, requiring salary range disclosure in job advertisements, granting employees the right to information on pay levels, and mandating regular gender pay gap reporting for larger companies, along with joint pay assessments. While Thailand's bill is carefully tailored to its national context and specific labour market dynamics, it incorporates many similar elements and best practices observed internationally, indicating an awareness of global standards and a desire to align with them. This convergence with international norms is important for Thailand's international trade relations, its attractiveness to foreign investment, and its reputation as a responsible actor in the global economy, as increasingly, international partners and investors consider a country's adherence to human rights and robust labour standards as a key factor in their engagement. By adopting such progressive legislation, Thailand positions itself as a leader in promoting fair and equitable workplaces in the ASEAN region.
