Important Considerations for Employment Contracts under Thai Law

Bangkok Post, Corporate Counsellor Column

Under Thai law, there are no requirements that employment contracts be made in writing. For some employers, this may create the perception that they can simply reach a cursory agreement with an employee on a few basic issues, such as job role and salary, and work out any other issues as they arise. In reality, this could not be further from the truth.

It is strongly advised that employers and employees have written contracts to clearly specify the terms and conditions of employment. Later, if any dispute arises, the parties can refer to a written contract to help determine the actual agreed-upon provisions.

In Thailand, employment contracts can be broadly categorized into two main types: fixed-term and open-ended. Accordingly, it is important to be aware of the type of contract being offered or entered into, as the rights and legal ramifications associated with each differ immensely.

Fixed-Term Employment Contracts

With provisions that specify the start and end dates of employment, this type of contract will end when the agreed period of employment expires, without the need for advance notice of termination. The contract cannot be terminated prior to the expiration of the agreed period, unless there is termination with cause.

The Supreme Court has ruled that fixed-term contracts must not contain any provisions that purport to allow an employer or an employee to terminate it prior to the expiration of the agreed period, or to extend the term. If it contains such provisions, it will lose its status as a fixed-term contract.

By way of an example, if a contract contains the provision that “the employment shall be for a period of 12 months, but either party may terminate the employment contract by giving the other party two months’ advance notice,” then it would not be effective as a fixed-term contract.

Another important consideration is the parties’ performance. Even if a fixed-term contract is in place, if the employee continues working and the employer continues paying wages after the expiration of the agreed period of employment, then the fixed-term contract would effectively convert into an open-ended contract.

There is no requirement to give advance notice of termination for fixed-term contracts. In practice, however, it is still advisable for employers to inform their employees, preferably in writing, that in accordance with the contract, the employment will expire at the end of the agreed period. This will help to ensure that everyone is on the same page.

Open-Ended Employment Contracts

Such contracts will only specify the commencement date of employment but not the end. An employee may resign or an employer may terminate the contract at any time, subject to the contract, their rights and obligations under law, and the employer’s Work Rules and Regulations.

For open-ended contracts, advance notice of termination is required, unless there is termination with cause and/or unless the employer is not required to provide advance notice of termination by law.

Necessary Provisions in Employment Contracts

To adequately safeguard the basic rights of both the employer and employee, employment contracts should always contain the following provisions:

  • Date the contract was made;
  • Names of parties to the contract;
  • Commencement date of employment;
  • Expiry date (for fixed-term contracts);
  • Probationary period;
  • Duties and responsibilities of the employee;
  • Wages, benefits and welfare;
  • Security deposit/guarantee (if applicable);
  • Working days, hours and holidays;
  • Position and right to change position;
  • Workplace address/location;
  • Non-competition and non-solicitation;
  • Confidentiality/non-disclosure;
  • Intellectual property;
  • Reference to Work Rules and Regulations; and
  • Termination of employment.

Language Requirements for Written Contracts

One of the most frequent questions clients ask is whether it is mandatory for contracts to be written in the Thai language. It is not.

However, if an employee is Thai and cannot understand English well enough to fully comprehend the terms of the contract, then it is strongly advisable to have the contract written in Thai or to have bilingual provisions. This way, both parties can understand the terms, and it guards against employees raising the issue that they misunderstood the terms in English.

Fair Contract Terms

Although an employer and employee are generally free to negotiate and agree to the terms and conditions of a contract, such terms and conditions must be fair.

If any terms or conditions result in the employer having excessive advantage over an employee, the court would be empowered to modify them as it deems fair and appropriate. Therefore, employers need to take great care in crafting their contracts to ensure legal compliance.

On March 4, 2025, Cambodia’s Ministry of Labor and Vocational Training (MLVT) issued Prakas No. 073/25 on Procedures for Resolving Individual Labor Disputes, replacing Prakas No. 318 on the same topic from 2001 and introducing significant changes to how individual labor disputes are filed, processed, and escalated. In addition, Prakas No. 073 outlines the roles and responsibilities of labor inspectors, the process for filing and handling complaints, and the steps for conciliation and further legal recourse, as described below. Filing a Complaint Any party to an individual labor dispute can file a complaint with the Labor Dispute Department of the MLVT or the Department of Labor at the capital or provincial level. Upon receiving a complaint, a labor inspector will review the case and may initiate either conciliation or a labor inspection. Invitation letters will be issued to the disputing parties to provide relevant information and documents. Conciliation Process Prakas No. 073 places strong emphasis on the conciliation process, introducing strict procedural rules and deadlines with clear consequences for noncompliance: If the claimant fails to provide required information within the specified deadline (or within three working days thereafter without reasonable excuse), the complaint is deemed void. If the respondent fails to attend the conciliation meeting within the deadline (or within three working days thereafter without reasonable excuse), the conciliation is considered unsuccessful, and the respondent is deemed guilty as claimed. Once all necessary information is gathered, a labor inspector will invite both parties to a joint conciliation meeting, which must be held within three weeks of the complaint being received. If the claimant fails to attend the meeting or sign the minutes without a reasonable excuse, the complaint is void. If the respondent fails to attend the meeting without a reasonable excuse, the conciliation is unsuccessful, and the respondent

On May 6, 2025, Cambodia’s Ministry of Labor and Vocational Training (MLVT) issued Prakas No. 112/25 on Overtime Work, Work on Paid Holidays, and Suspension of Weekly Days Off, which outlines specific conditions, formalities, and procedures in relation to working overtime, work on paid holidays, and suspension of weekly days off. Overtime Work Employees may be requested to perform overtime work based on the operational needs of the employer, particularly in the following circumstances: When undertaking special assignments related to inventory and balance sheets, liquidation deadlines, and closing of accounting books. In cases of excessive workload arising from exceptional circumstances where alternative measures are not feasible for the employer. However, the overtime work must be conducted voluntarily and must not be enforced through coercion or disciplinary action. Although this new prakas on overtime work does not specify the maximum allowable hours of overtime work, the Labor Law states that overtime must not cause total working hours to exceed 10 hours per day, except in cases of disaster prevention or rectification. Work on Paid Public Holidays Employees are entitled to paid public holidays announced annually by the MLVT. However, when work cannot be suspended, employees may be requested to perform work on paid public holidays on a voluntary basis. Suspension of Weekly Days Off When urgent work is required to prevent imminent accidents or to repair damage to materials, facilities, or buildings, weekly days off may be suspended for up to two nonconsecutive days per month. This applies to both employees of the affected enterprise and those of external entities engaged in the repairs of the affected enterprise.

On May 6, 2025, Cambodia’s Ministry of Labour and Vocational Training (MLVT) issued Prakas No. 113/25, introducing new obligations for enterprise owners and directors regarding the use and maintenance of enterprise payroll books. Under this prakas, enterprise owners or directors are required to: Utilize and maintain the enterprise payroll book in accordance with the official template provided by the MLVT. Make the enterprise payroll book available to labor inspectors for annotations related to compliance with labor laws and regulations. Review and adjust (if necessary) internal practices based on any findings, recommendations, and restrictions issued by labor inspectors during inspections. The official enterprise payroll book template can be downloaded via the ministry’s Labor Automated Central Management System (LACMS). Additional requirements include: Retention of supporting documents related to the payroll book at the enterprise’s head office to facilitate inspections. Preservation of completed payroll books for a minimum of three years after their closure. Downloading a new payroll book from the LACMS once the current one is fully used. Labor inspectors are authorized to conduct inspections of the payroll book and related documentation at any time. Noncompliance with the provisions of Prakas No. 113/25 may result in significant monetary penalties, as stipulated in Cambodia’s Labour Law. This prakas also repeals Prakas No. 268, dated October 11, 2001, and any provisions in related regulations that conflict with Prakas No. 113/25. All enterprises are strongly advised to comply with the new requirements and begin using the updated enterprise payroll book template from the LACMS to avoid potential penalties.
