To ensure that every employer complies with the Labour Protection Act B.E. 2541 (1998) ("Act"), the Act has prescribed the procedures for the inspection of employment practices of Labour Inspection officials who have the right to enter into any workplace during work hours and request documents, take photographs, make copies of documents and generally inspect the workplace.

Full Update 

The newly amended Labour Protection Act B.E. 2551 (2008) has further specified procedures for employers employing more than 10 employees in order to facilitate inspection by Labour Inspection officials. This includes submitting a form clarifying the details of employment and working conditions to the Director General of the Department of Labour Protection and Welfare (the "Director General").

The forms should include and clarify the following details:

General Information

  • Name and address of the employer
  • Type of office

Number of Employees

  • Total number of employees
  • Number of male employees
  • Number of female employees
  • Number of young employees (ages from 15 to 18 years old)

Employment status and working environment

  • Total working days per week
  • Normal working hours per day
  • Break hours per day
  • Holidays per year
  • Public holidays per year
  • Annual leave per year (minimum to maximum)
  • Minimum and Maximum Wage rates of the following:
    • Monthly salary
    • Daily wage
    • Hourly wage
    • Average wage per unit of work performed

The form (in Thai version) will be distributed to every employer in December every year, and the employer has a duty to complete the form and return the same to the Director General by the end of January of the following year.

The employer must notify the Director General in writing within a month following the date of any change to the submitted information regarding the employment status and working environment.

A fine not exceeding THB 20,000 will be imposed on an employer who fails to submit the form or to report any such changes within the specified period.
