The regulation governing working hours in Thailand
Thailand working hours are a key aspect of employment law in the Kingdom. For international companies operating in Thailand or foreign employees working under Thai labor contracts, knowing the rules on Thailand working hours is crucial to avoid legal risks. The Labor Protection Act B.E. 2541 (LPA 1998), which is the principal legal framework governing employment conditions in Thailand, clearly defines standard working hours (from section 23 to 25), rest periods (Section 27 to 30), overtime obligations (section 25 to 63), and special rules for certain industries. This Act was promulgated under the constitutional authority granted by the Constitution of the Kingdom of Thailand B.E. 2540 (1997), and remains in force under subsequent constitutional revisions.
In particular, the Labor Protection Act serves to implement the principles laid down in Section 44 of the Thai Constitution, which provides that every person shall enjoy rights to fair and safe working conditions. Furthermore, the law aligns with Thailand’s international obligations under conventions of the International Labour Organization (ILO), including Convention No. 1 on Hours of Work (Industry) and Convention No. 14 on Weekly Rest (Industry), which Thailand has ratified.
This article provides a detailed legal overview of Thailand working hours, under Thai labor law. It is imperative that individuals setting up businesses or employing staff in Thailand know this framework to avoid labour disputes.

Legal framework for working time in Thailand
Legal definition of standard working hours in Thailand (Section 23 to 25 of LPA)
Under Section 23 of the Labor Protection Act B.E. 2541, the standard Thailand working hours must not exceed eight hours per day and forty-eight hours (48H) per week. In practice, however, the typical working hours are 40 hours per week. This means that a regular working day usually lasts eight hours, although variations are possible depending on the nature of the job. For example, Section 24 and 25 allows flexibility for jobs that require continuous operations or shifts, such as hospital staff or security guards.
In cases where work is hazardous or physically demanding, section 23 limits the Thailand working hours to seven per day and forty-two per week. The types of work that qualify as hazardous are determined by ministerial regulations, such as Ministerial Regulation No. 2 (1998), which includes tasks involving chemical exposure or high-risk machinery.
Therefore, employers must evaluate the nature of each job to determine the applicable maximum Thailand working hours. Failing to comply can lead to administrative fines or even criminal penalties.
Overtime beyond standard working hours under Thai law (Section 25 & 63 of LPA)
Overtime is tightly regulated under Thai labor law. According to section 25 the Labor Protection Act, an employer may request an employee to work beyond normal Thailand working hours only if the employee gives consent.
The law requires employers to pay a premium for overtime work. Under Section 63, employees are entitled to at least 150% of their normal hourly wage for overtime on regular working days. On holidays, the rate rises to 200% or more. These provisions are reinforced by Ministerial Regulation No. 10 (1998), which sets out how to calculate overtime compensation.
Importantly, there is no absolute maximum on the number of overtime hours per week, but the employer must ensure that total Thailand working hours do not become excessive or violate health and safety regulations. In practice, the Labor Inspectorate may intervene if abuse is suspected.
Rest, holidays, and weekly limits on Thailand working hours
Thailand working hours must include breaks to ensure worker health. Section 27 of the Labor Protection Act mandates a rest period of at least one (1) hour after five consecutive hours of work. This rest can be split into multiple breaks if necessary.
In addition, Section 28 guarantees that employees are entitled to at least one (1) day off per week. This weekly rest day should ideally be consistent, and most employers choose Sunday. Employers cannot force employees to work on their day off unless urgent business needs arise and the employee consents. In such cases, special holiday pay must be provided.
The law also provides for public holidays and annual leave. Section 29 stipulates that employers must grant at least thirteen (13) public holidays per year. After one year of continuous service, Section 30 entitles employees to a minimum of six days of paid annual leave. These protections ensure that Thailand working hours are applied fairly and uniformly.
Sector-specific variations and special protections
Industries outside the scope of general working hours regulations
Yes, Thailand working hours are subject to variation depending on the sector or employment classification. The Labor Protection Act provides exceptions or specific rules for certain categories of work. For instance, employees in sea transport, agriculture, and domestic service fall under special provisions.
In the hotel and tourism sectors, night shifts and irregular Thailand working hours are common. In such cases, employers must still comply with the maximum weekly limits and rest provisions but may implement shift systems with prior approval and proper documentation.
Foreign employees and executives working under employment contracts governed by the Civil and Commercial Code (rather than the Labor Protection Act) may be treated differently, although courts increasingly interpret ambiguous cases in favor of the employee.
Protection of specific groups under the Labour Protection Act (Section 39 & 44 of LPA)
Thai law imposes stricter rules on Thailand working hours for vulnerable employees. Section 39 prohibits employers from requiring pregnant women to perform work involving long periods of standing, night shifts, or hazardous conditions. These employees must not work overtime or on holidays unless they expressly consent and the work is safe.
For minors, the rules are even more protective. Section 44 bars employers from hiring children under fifteen. For those aged fifteen to eighteen, Thailand working hours must not exceed eight hours per day or forty hours per week, with no night work or overtime unless permitted by the Director-General of the Department of Labour Protection and Welfare.
These provisions reflect Thailand’s commitment to international labor standards, including conventions from the International Labour Organization (ILO) that Thailand has ratified.

Employer obligations and enforcement mechanisms
Documentation and compliance requirements for employers (Section 108 to 115/1 of LPA)
Thailand working hours must be documented accurately. Section 108 to 115/1 of the Labor Protection Act requires employers to maintain detailed records of working time, rest breaks, holidays, and overtime. These records must be kept for at least two years and be available for inspection by the Labor Inspector.
Companies with more than ten employees must also display working rules at the workplace, including the schedule of Thailand working hours and rest periods, under Section 108. Failure to comply can result in fines.
Employers are advised to use electronic timekeeping systems to ensure transparency and legal compliance. In labor disputes, courts often rely on employer records to determine whether workers received proper compensation for overtime and holidays.
Enforcement of working hours regulations violations in Thailand (Section 144 to 146 of LPA)
Violations of Thailand working hours regulations can trigger administrative and criminal penalties. Under Section 146, employers who fail to comply with the law on Thailand working hours, overtime pay, or rest periods may face fines up to 20,000.
Repeated or severe violations can lead to imprisonment under Section 144. For example, if an employer consistently denies mandatory weekly rest days or pays below the legal overtime rate, the Labor Inspectorate may prosecute the case.
In addition to legal sanctions, non-compliance with Thailand working hours rules may lead to reputational damage and labor court litigation. Employees can file complaints with the Ministry of Labour, and inspectors have authority to conduct workplace audits.
Adapting to Thai labor law: Guidance for foreign employers
Foreign Employers’ Obligation to Comply with the LPA
Foreign companies operating in Thailand must tailor their HR policies to local labor laws. While global corporate practices may allow for flexible work arrangements, they must still align with Thailand working hours legislation. For example, remote work or flexible schedules remain subject to daily and weekly limits under section 23 to 25 of the Labour Protection Act 1998
Work contracts should clearly define Thailand working hours, rest days, and overtime policies. It is also recommended to include clauses on timekeeping and dispute resolution. Legal counsel can assist with adapting templates to comply with Thai regulations.
Failure to observe local rules on Thailand working hours can lead to legal liability and employee dissatisfaction. Given the increased enforcement by labor authorities, proactive compliance is essential.
