This page is an English summary of our Thai article on employment contracts. It is grounded in the Civil and Commercial Code and the Labour Protection Act so businesses can see which terms are commercial choices and which terms are fixed by Thai law.
Core legal framework
Under section 575 of the Civil and Commercial Code, an employment contract is an agreement under which the employee works for the employer and the employer pays wages for that work. Thai law does not require every employment contract to be written to exist, but written terms are still the safest approach because they reduce factual disputes over duties, wages, probation, benefits, and termination procedure.
What every employment contract should cover
- Job title, reporting line, and a realistic description of duties.
- Wage rate, payment schedule, benefits, and any lawful allowances.
- Normal working hours and rest periods.
- Weekly holidays, traditional holidays, annual leave, sick leave, and maternity leave.
- Probation terms, confidentiality obligations, and post-employment return of company property.
- Termination procedure, notice period, and how final payments will be handled.
Statutory minimum standards that contracts cannot undercut
Section 23 of the Labour Protection Act caps normal working hours at not more than eight hours per day and forty-eight hours per week in ordinary cases, with lower limits for work harmful to health and safety. Section 28 requires at least one weekly holiday per week. Section 29 requires at least thirteen traditional holidays per year, including National Labour Day, and section 30 gives annual leave of at least six working days after one uninterrupted year of service.
Leave rights also matter at the drafting stage. Section 32 allows sick leave as long as the employee is actually sick, with section 57 requiring wage payment for up to thirty working days of sick leave per year. Section 41 allows maternity leave of up to ninety-eight days per pregnancy, and section 59 requires wages for maternity leave up to forty-five days per year.
Probation and notice
Section 17 treats a probationary contract as an indefinite-period contract. That means probation does not remove the normal Thai-law notice framework by itself. If the employment is not for a fixed term, termination usually still needs written advance notice at or before a wage payment date, unless the employer chooses to pay in lieu of notice or relies on a lawful immediate-termination ground.
Unfair or overreaching clauses
Section 14/1 gives the court power to limit the enforcement of an employment contract, work rule, regulation, or order if it results in exploitation of the employee. In practice, this matters when employers copy broad clauses that waive statutory rights, impose one-sided penalties, or go further than necessary on restrictive covenants. A contract can protect the business, but it should still be fair and reasonable under Thai law.
Practical takeaway
A strong employment contract should do two things at the same time: document the real commercial expectations of the role and stay above the minimum rights Thai law guarantees. Most problems come from unclear duties, copied clauses that ignore statutory standards, or termination wording that does not match how the company actually pays wages and manages staff.
