Thailand has no consolidated code of labour law. The most important single Act in this area is the Labour Protection Act (1998). However, other provisions regarding labour law are to be found in the Civil and Commercial Code, the Labour Courts Act, the Labour Relations Act, the Factories Act, the Social Security Act, the Workmen’s Compensation Act, the Provident Fund Act, and the Safety, Health and Workplace Act, and regulations issued pursuant to those Acts.


The Labour Protection Act The Labour Protection Act came into force on August 19, 1998.


Who is an ‘employer’? An employer means a person who agrees to employ employees to work by paying wages and includes: (1) A person who is authorized to employ people on behalf of the employer, and (2) where the employer is a juristic person, a person who is authorised to act on behalf of the juristic person and a person appointed by an authorized juristic person to act on his/her behalf.


Note that a business is also deemed to be an ‘employer’ if a contractual employer has sub-contracted the provision of work and payment of wages to it. Such an employer must also provide the employees (of the contractual employer) with the same employment protection measures as the employees’ contractual employer.


Who is an ‘employee’? An employee means a person who agrees to do work for an employer in return for wages, regardless of the description of his status.


Note that employees in certain specified occupations, including those in agriculture, fisheries, the transporting or loading of goods for seagoing vessels, and other categories as prescribed by regulations, are subject to other forms of employment protection outside the Act. The Act also does not apply to central or local government entities or state enterprises – such persons have employment rights similar to the LPA under separate legislation.


A regulation has been issued exempting employers who are non-profitmaking organizations from the LPA obligations for payment of severance pay, and the obligation to contribute to the government provident fund (see below).


The Act applies to all other employees, as defined above.

What is an employment agreement? An employment agreement means a written or oral agreement which is clearly stated or implicitly understood, where a person referred to as the employee agrees to do work for another person referred to as the employer, and the employer agrees to pay wages throughout the period of work.

Hours of work An employer must notify the working hours to the employee. It must state the beginning and end of working hours in each day, not exceeding the hours for each type of work as prescribed in regulations, and not exceeding eight hours a day. Where the work does not last eight hours in a day, the parties may agree to add the hours to another day, provided it does not exceed nine hours in a day and when aggregated for the whole week, does not exceed 48 hours. This is except for certain types of work that may damage the health and safety of the employee, then in accordance with regulations an employee must not work more than seven hours in a day and not exceeding 42 hours in total per week.

Where the parties agree to increase the working hours on another day as above, and this exceeds eight hours in a day, the employer must pay wages of not less than 1.5 times the normal hourly rate for the excess hours, to an employee who works on a daily basis or who work on an hourly rate, or not less than 1.5 times the normal wages paid to those who work on a piece work basis.


Where the employer is unable to state the beginning and end of the working hours of each day, due to its nature, or the working conditions for certain types of work, the parties may agree to work not more than eight hours in a day and not more than 48 hours in a week.


Minimum wages Historically, Thailand had a policy of minimum wages and annual increases on a province-by-province basis. This has now been replaced by a national minimum wage policy. With effect from 1 January 2013, the minimum wage is 300 Baht daily throughout the country


The minimum wage applies to all categories of employees, except for those in certain excluded industries, namely: agriculture including cultivation, fisheries, forestry, livestock farming, and other industries as prescribed in regulations. The rates are based on a day's work, assessed as follows:


1.    A seven hour day, for work that is likely to be dangerous to health or physically dangerous, as defined in regulations.


2.    An eight hour day for industrial work or work in transport.


3.    A nine hour day for work in commerce, or other work not included in (1) or (2) above.


Where the normal working hours of an employee exceed those referred to above, then the minimum wage applicable must be increased proportionately, unless the employee receives overtime pay, in accordance with regulations. An employer is obligated to pay the minimum wage applicable, and violation is an offence punishable by imprisonment or a fine.


The employer must display the notification in a conspicuous place at the workplace for the information of employees, during such time as the notification remains in effect.


Note also that the National Wages Committee has power to prescribe minimum wages for certain categories of employee in specific industries based on skills.

Entitlement may depend on the employee passing specified tests and working in a particular position.


For example in August 2016, minimum wages were fixed for certain categories of employee in the following industries:


1. electrical industry and electronics;


2. motor vehicle industry;


3. logistics industry;


4. parts and spare parts of motor vehicles industry; and

5. jewelry industry.


The rules applicable to any particular industry, or category of employee, must be consulted to ascertain the current entitlements.


Overtime An employer may not compel an employee to work overtime, and an employee’s consent to work overtime is required. Overtime hours must not exceed the number stipulated by the Ministry of Labour. An employee employed to work in the following work, is not entitled to claim overtime payments or holiday overtime payments, but an employee who is employed to work in (3) (4) (5) (6) (7) (8) or (9) is entitled to payment, according to the hourly rate for a working day and the number of working hours:

In such cases, the employer may instruct the employees to work during a holiday to the extent that it is necessary.

The employer is obliged to pay wages during sick leave for up to 30 days per year. Where absence is due to work related sickness or injury, or maternity leave, this does not count as absence through illness. 


Work stoppages Where the employer has to stop the whole or part of its operations temporarily, and this is not due to force majeure and this affects the employees, the employer must pay not less than 75% of an employee’s wages before the operations stop, for the whole period of the interruption. An employer must give not less than three working days advance written notice to the employees and the labor inspector regarding the stoppage of operations.

Reasons for dismissal Where an employer dismisses an employee for a permitted statutory reason, that is a reason that exempts the employer from paying severance pay, then the reasons for such dismissal must be stated in the dismissal notice. If the reasons are not so stated, then the employer will be estopped from raising them as a defence in any proceedings subsequently brought by the employee.


Where dismissal is not permitted Note also that an employer may not dismiss an employee for the reason of pregnancy, or for trade union membership or trade union activities.


Notice period When an employment contract for a fixed period has expired, the employment will end without any notice being necessary.


Where the employment contract that does not specify the period of employment, either party may terminate it by giving to the other written notice, within, or before the wages are due, with the effect that employment is terminated when the next payment is due, but not more than three months notice need be given. A probationary period is deemed to be a non-specified employment contract.


In the case of termination, the employer must pay wages due to the date employment is ended, as notified, and the employee may leave.


Payment may be given in lieu of notice.


No notice is required where employment is terminated for permitted cause under either the LPA, or the Civil and Commercial Code.

30 days’ pay


Exceeding 1 year but less than  3 years

90 days’ pay


Exceeding 3 years but less than 6 years

180 days’ pay


Exceeding 6 years but less than 10 years

240 days’ pay


10 years employment or more

300 days’ pay


No liability for severance pay No severance pay is due:


  1. where the employment is for a fixed duration and employment expires at

the end of the contract period, provided the employment is for a particular project that is not in the normal course of business of the employer; or


2. where the work is periodic in nature and with a fixed term or ending on its completion, or seasonal work and the employment is performed during that season


and in each case, the employment was for a fixed period of not more than two years, and agreed to in writing by both parties when the contract was made.


Unfair dismissal Under the Labour Courts Act, if in the opinion of the Labour Court the employee has been unfairly dismissed, the court has power to order the reinstatement of the employee at the same wage rate that previously applied. If the court decides that the parties cannot work together, then the court will assess the employee’s losses taking into account his age, length of service, hardship at the time of dismissal, the reasons for the dismissal and the compensation that the employee is entitled to receive.


In trying a case of dismissal or other labour case, the Labour Court must take into account the conditions of work, the cost of living, the hardship of the employee, wages rates or the rights or benefits of employees working in the same type of business, the status of the business and general economic and social conditions, in order to be fair to both parties. 


Appeals Appeals from the judgments of the Labour Court are made direct to the Supreme Court.


Payment of annual holiday and accumulated holiday pay on dismissal Where the employer terminates employment not for permitted cause, it must pay accumulated annual holidays to employees, duly pro-rated. Where either employee or employer terminates the employment contract, regardless of whether termination was for permitted cause, the employer must pay accumulated holiday leave which the employee is entitled to receive.


Dismissal due to restructuring or modernization If dismissal occurs due to restructuring of the business or change in the machinery or technology, then 60 days advance notice of dismissal must be given to the employees and to the Labour Inspection Office. If not, then 60 days special compensation is payable to an employee. In addition, dismissed employees with over six years service are entitled to special compensation of 15 days pay for each year of service, subject to a maximum payment of 360 days pay.


Dismissal due to re-location of the business When an employer relocates its place of operations or business and the relocation affects the ordinary living conditions of the employee or his family, the employer must notify the employee of the relocation, not less than 30 days prior to the date of relocation. Where the employee does not wish to work for the employer at the new location, he has a right to terminate his employment contract within 30 days from the notified date of relocation. The employee is then entitled to special severance pay of not less than the severance pay which an employee is entitled to if dismissed without permitted cause.

Where the employer does not notify the employees in advance, it must pay special severance pay, at the most recent rate for a 30 day period, or the most recent 30 days wages to an employee who is paid by piecework.


Payment must be made by the employer within seven days from the date that the employment is terminated. The employee is not required to give notice of such claims to the employer.


If the employer fails to make payment, the employee may complain to the Labor Welfare Committee.


Date for payment Any wages, overtime pay, holiday pay or overtime holiday pay due must be paid to the employee within three days of dismissal.


Employer to pay interest in case of default Where an employer does not return security money, or does not pay wages, overtime pay, holiday pay, and holiday overtime pay within the specified date, or severance pay, special severance pay without notice or special severance pay, the employer must pay the employee interest of 15% per year for the period of default.


Transfer of employment Where employees are transferred, whether on the sale or transfer of a business or otherwise, the new employer is obliged to accept all the rights and obligations of the former employer, in relation to the transferred employees.

The Act contains the following key definitions:


"Homework" means work that an employer in an industrial business has assigned to a person taking work for production or assembly outside the business establishment of the employer, or other work as set out in regulations.


"Homeworker" means a person or a group of persons who agrees with an employer to undertake homework.


"Employer" means a business operator who agrees to employ a homeworker, regardless of whether the assignment of the job will be made through him, his representative or by a sub-contract.


Interpretation Any claim or acquisition of a right under the Act does not deprive a person of any right as a homeworker under other law.


Court with jurisdiction All cases arising from disputes between employers and homeworkers or their heirs relating to rights under the Act are under the jurisdiction of the Labour Court.

Power to vary contract terms Where the employment agreement or terms in a document relating to the taking of homework has resulted in the employer having an unreasonable advantage over the homeworker, the Labour Court has power to order only part of the employment agreement or terms that are fair and reasonable to be enforceable.


Duty to prepare documents An employer must prepare documents relating to the taking of homework in Thai language; one copy for the homeworker and the other for retention by the employer when the work assignment is made provided it must be available for inspection by a Labour Inspector during working hours.

Where work cannot be completed within the agreed period Where there are reasonable grounds to expect that work taken as homework cannot be completed within the prescribed time, the homeworker must notify the employer as soon as possible so that an agreement to extend the time for delivery of the work can be made.


Where the employer does not agree to extend the time for delivery, and is likely to sustain loss from a delay in such delivery through no fault of the employer, the employer has the right to terminate employment and assign the work to another person.


Right to claim damages Termination of employment as above does not deprive a party from claiming damages against the party liable for such fault.


Other rights to terminate employment Where the materiality of the employment lies in the knowledge and know-how of the homeworker, and the homeworker is deceased or cannot continue to work on such assignment without fault, the employment shall end. But if part of the job has already been completed and considered to be beneficial to the employer, the employer must accept the work and pay wages in accordance with the proportion of the work completed.


Performance guarantees and security deposit An employer may not demand or accept a performance guarantee or security deposit against loss resulting from work by a homeworker unless without this; the category, quantity or value of the assignment worked on may cause loss to the employer, in which case the category, quantity or value of the work in relation to which a performance guarantee may be demanded must be in accordance with regulations.


An employer must return the performance guarantee or security deposit within seven days from the date on which the employer has received the completed work.


Supply of raw materials, equipment or other things Where the employer supplies raw materials, equipment or other things for use in the work, the homeworker must use these carefully and economically and unless agreed otherwise, must return these after completing the assigned work.

(1)    payment of income tax legally required from the homeworker;


(2)    other payments as provided by law;


(3)    compensation for loss to the employer as a result of an intentional or grossly negligent act of the homeworker, but this must be consented to by the homeworker,

Dangerous raw materials, equipment or other things An employer may not supply or deliver raw materials, equipment or other things for use in carrying out assigned work, that may be dangerous to the homeworker, persons in the home, and persons coming into contact with it, including neighbours.


Employer’s duty to warn of danger The employer must notify the homeworker of information relating to danger which may occur as a result of the use of raw materials, equipment or other things for use in carrying out the assigned work, and procedures to protect himself from such danger and to provide adequate safety protection equipment suitable to the nature of the work.


A homeworker must use safety protection equipment provided by the employer and upon completing the assigned job, the remaining equipment must be returned to the employer.


Employer’s obligations regarding medical treatment, etc. The employer is liable for medical treatment costs, cost of capacity rehabilitation and funeral allowances, where the homeworker has suffered an accident, illness, disability or death resulting from the use of raw materials, equipment or other things supplied or delivered by the employer for use in carrying out the assigned work, or as a result of the failure of the employer to provide safety protection equipment, or in the case of a job-related accident at the workplace, provided that payment of medical treatment costs, costs of capacity rehabilitation and funeral allowances must be in accordance with rules specified in regulations.


These provisions do not apply where the accident, illness, disability or death results from the intentional act or gross negligence of the homeworker.


Regulatory authority A regulatory authority will be set up, called the Committee for Protection of Homework Employment. Amongst other things, the regulator can determine minimum wage rates which are not to be lower than the wage rates fixed under the Labour Protection Act.


Complaint to a Labour Inspector Where an employer has failed to pay money to a homeworker in breach of the Act, the homeworker may complain to a Labour Inspector. If the homeworker deceases before the complaint is submitted or during the course of its consideration, his heir may continue with it. Complaints are generally to be determined within 30 days of submission. Where the Inspector makes and order for the employer to pay money, it must be paid within 30 days. Either party has a right of appeal to the Labour Court exercisable within 30 days. Where the employer appeals, it must deposit money in the same amount as that due for payment before the appeal is accepted.


Powers of Labour Inspectors The Act sets out the inspector’s powers of entry into buildings, to seize documents, take samples, to require any person to make a statement or supply documents, or order an employer to comply with the Act.


Fines and punishment the Act imposes fines and imprisonment for breaches of duties imposed under the Act, including failure to comply with the order of a Labour Inspector. Where the offender is a juristic person, the managing director, manager or any person responsible for its operations is equally liable unless he can prove that he played no part in the offence.


Priority of debts in insolvency or otherwise Under the general law, a preferential creditor has rights against the property of his debtor in priority to ordinary or deferred creditors. With regard to any monies that an employer is liable to pay under the LPA or contributions that the employer has to pay into the Social Security Fund, the employee or Department of Welfare and Labor Protection has a preferential right over the property of the employer, with equal ranking to taxes that the employer is obligated to pay.


Power of the court to review employment agreements Where the employment contract, work regulations, rules, or employer’s orders benefit the employer excessively, the court has power to issue an order regarding those employment contracts, working regulations, rules, orders to be enforced only in a reasonable and fair manner.


Enforcement of LPA obligations To enforce obligations under the LPA, an employee may bring a complaint to the Labour Inspection Office, alleging that an employer has not complied with any provision of the Act. A Labour Department Inspector will investigate the complaint, and issue a ruling within 60 days of the complaint being made. Either the employee or the employer may appeal to the Labour Court, if he is dissatisfied with the decision of the Inspector.


Alternatively, an employee may issue proceedings in the Labour Court, claiming a severance payment, damages for unfair dismissal, unpaid wages, unpaid holiday pay, etc. There is also a scale of fines or imprisonment for violations of certain sections of the Act. Non-compliance with an order made by an Inspector is also an offence.


Fines and imprisonment The LPA has a detailed list of fines and imprisonment that apply to breaches of duties imposed under the Act.


Safety, Health and Workplace Act (2011) In July 2011, the parts of the Labour Protection Act that enabled the Ministry of Labour to issue regulations for the health and safety of employees were repealed. These were replaced by a new Safety, Health and Workplace Act (2011). The purpose of this Act is to impose duties upon employers for safety and health in places of work.


Included employers The Act applies to all employers, but not to central, regional or local authorities, or other employer exempted under regulations.

Non-compliance by employer: Where the employer does not comply with the order of a safety inspector, where there is a possible cause of a serious accident where the Labour Welfare and Protection Department should intervene, the Director General may order the safety inspector or an individual to rectify matters to comply with such order. In such case, the employer is liable for the costs incurred. Prior to such action, a written warning must be delivered to the employer to require compliance with the order of the safety inspector within a specified timeframe. Such warning can be issued with the order of the safety inspector.


Seizure of the employer’s assets where the employer fails to pay for costs incurred The Director General may order seizure, impounding and disposal of assets of employers who fail to pay expenses incurred under the previous paragraph as necessary to cover the actual expenses incurred.

Punishment The Act imposes fines and in some cases, daily fines and imprisonment for breaches of duty under the Act. Where the offender is a juristic person, if the offence is the result of an order or an act of any person, or a result of the failure to order, or act on the duty of a managing director or any individual responsible for the operation of such juristic person, that person is liable to punishment in the same way.


Social security Under the Social Security Act, all employers are liable to register with the social security fund, regardless of the number of employees. Employers, employees and the government itself contribute to the social security fund. Each of the employer and the employee pays contributions of 5% of salary (up to a fixed maximum) into the Social Security Fund every month. The fund pays benefits to those registered or their families in cases of illness, injury, disability or death suffered not in the course of employment, child welfare, unemployment, or retirement pension (the latter is only payable upon permanent retirement).


Workmen's compensation Under the Workmen’s Compensation Act, all employers are liable to register with the workmen’s compensation fund, regardless of the number of employees. The employer pays a percentage of an employee’s salary into the fund annually. The contributions are based on the hazards involved in the business and are different. Under the Act, an employee who is injured or becomes ill or dies during the course of employment, is entitled to medical, disability and/or death benefit in accordance with fixed rates. The fund will pay benefits subject to receiving evidence that establishes the right to make a claim. The amount of compensation is relatively small when compared to that paid in industrialized nations.


Trade unions and employers associations The Labour Relations Act (1975) sets out a comprehensive framework of rules for employees and employers to negotiate labour disputes. The Act also provides for the registration of trade unions, trade union federations, employers’ associations and employers’ federations. Employees who engage in trade union activities may not be disciplined or dismissed for such activities. Generally speaking, trade unions are not very active in Thailand.
