Understanding Warning Letters and Employment Termination under Thailand’s Labor Law
For businesses operating in Thailand, managing employment matters in line with local labor laws is essential. A critical aspect is the proper use of warning letters as a step before possible termination. This process, outlined in the Labour Protection Act B.E. 2541 (1998), helps maintain fairness in the workplace. At Sukhothai Interlaw, our team has guided employers in labor matters for over 30 years, providing trusted expertise.
When Can Employers Use Warning Letters?
In Thailand, employers may issue a warning letter when an employee repeatedly breaks company policies. This warning acts as a formal notice, giving the employee a chance to correct the issue. In more serious cases, the law permits immediate termination without needing a warning letter first.
What Should a Warning Letter Include?
A well-prepared warning letter includes specific details so there is no misunderstanding. Here’s what to include:
- Date: Note the exact date of the warning letter’s issue.
- Employee Information: List the employee’s full name and role.
- Incident Details: Describe the behavior or incident that goes against company policy.
- Reference to Policy: Clearly state which company rule was broken.
- Next Steps: Explain that further violations could lead to disciplinary action.
The letter should stay on record for one year from the violation date itself. For clarity, it’s a good idea to have the employee acknowledge the warning by signing it. If they decline, you can read the letter in front of two witnesses who then sign as confirmation of the warning’s delivery.
Special Rules for Employee Committee Members
If the employee is part of an Employee Committee, additional steps apply. Thai law requires that the employer get approval from the Labour Court before any disciplinary action, including issuing a warning letter. This extra step is intended to ensure fair treatment of employees serving on committees.
Employee Rights in Business Relocation or Structural Changes
If a company relocates and this significantly impacts an employee’s routine, employers are expected to provide at least 30 days’ notice. Without this, employees are entitled to a payment equivalent to 30 days’ wages. Employees who choose not to relocate with the company can end their employment and qualify for severance.
Similarly, if a business downsizes due to new technology or structural changes that lower staffing needs, employers should provide affected employees and the Labor Inspector with a minimum 60 days’ notice. If this notice is not given, the company must pay compensation equal to 60 days of wages. Employees who have been with the company for six years or more are eligible for an additional severance benefit at 15 days’ wages for each year beyond six, up to a maximum of 360 days’ wages.
