What is Thailand Annual Leave Law?

The Thailand annual leave law for employees is mainly governed by the Labour Protection Act B.E. 2541 (1998) specifically Section 30 which ensures any employee who has worked for the same employer for at least 1 year gets at least 6 working days of paid leave annually. 

Employees are ensured enough time off for rest and recovery by this law, reflecting that Thailand values fair labor practices and standards. This provision emphasizes importance placed on employee rights in Thailand and contributes to Thailand’s reputation for protecting employee benefits in the workplace. 

Who is Eligible for Annual Leave?

  • Employees who have worked for the same employer for 12 consecutive months are given 6 paid days of statutory annual leave. 
 
  •  Workers who have worked for less than 1 year are not lawfully granted annual leave, but many businesses let them have pro-rata annual leave as goodwill.  
 

Obeying the leave policy in Thailand that supports pro-rata leave can help to improve employee’s satisfaction and retention.

Employer Obligations Under Thailand Annual Leave Law

Employers must follow these requirements: 

  • Advance Leave Scheduling: Inform the employees well in advance of their leave dates. The law does give employers power to decide leave dates; however, it recommends a cooperative arrangement between both parties. 
 
  •  Save proper leave records: Keeping detailed logs makes it easy to handle leave entitlements and prevent disputes. 
 
  • Unused leave pay on termination: Employees are supposed to be compensated in cash for any unused annual leave when their employment ends, as required by Section 67. 
 
  • Carry-forward unused leave: Only with the agreement of both the employer and the employee can unused annual leave be carried over to the next year. These details must be precisely documented. 
 

Not adhering to these rules can result in fines of up to THB 20,000 (Section 146). Employers can follow all the rules easily by going through the Thailand Labour Law.
