Workplace Harassment Complaint Checklist for Thailand
Document checklist for filing a workplace harassment or discrimination complaint through internal channels, Labor Inspector, or Labor Court.
Document Checklist
Detailed incident documentation (dates, times, locations, descriptions)
Maintain a contemporaneous log of every incident. Include what happened, who was involved, where it occurred, and how it affected you.
Witness statements or contact information of witnesses
Identify colleagues who witnessed the incidents. Written statements are ideal but contact details are sufficient initially.
Copy of internal complaint filed with HR/management
Keep a copy of your written complaint and proof of submission (email receipt, signed acknowledgment). This demonstrates you attempted internal resolution.
Medical records or psychological assessment (if applicable)
If the harassment caused physical or psychological harm, obtain medical documentation. This supports claims for damages.
Labor Inspector contact information and complaint form
Department of Labor Protection and Welfare — file at any provincial labor office. Hotline: 1506. Filing is free.
Legal representation (recommended for Labor Court filing)
While not required (Labor Court provides free counsel), having a lawyer strengthens your case. Budget THB 20,000–100,000.
Employment contract and company policy documents
Include your employment contract, company handbook, anti-harassment policy (if any), and work rules.
Screenshots of messages, emails, or other communications
Save all electronic evidence. Take screenshots and back up to personal storage outside the workplace.
Passport/ID and work permit (for foreign employees)
Common Mistakes to Avoid
Resigning before filing a complaint — this weakens your position and may forfeit severance and reinstatement rights.
Not documenting incidents immediately — delays reduce the evidentiary value of your account.
Only filing verbally — always submit written complaints for a paper trail.
Not keeping copies of evidence outside the workplace — employers may restrict access to work systems.
Waiting too long — labor claims have time limits that vary by type of complaint.
Helpful Tips
The Labor Court does not charge filing fees for employees — the system is designed for accessibility.
You are legally protected from retaliation for filing a harassment complaint.
The Gender Equality Act B.E. 2558 (2015) provides additional protections against gender-based discrimination.
Consider filing with both the Labor Inspector and NHRC simultaneously for discrimination cases.
Free legal aid is available through the Thai Bar Association (Lawyers Council of Thailand).
