Is dismissing an employee in Thailand expensive?
More than most bosses expect. Statutory severance rises in steps with length of service, and dismissal without proper cause can carry additional compensation on top. The employment arrangement has to be designed before you hire, not patched up after something goes wrong.
Does the company have to pay social security for its employees?
Yes. Once you take someone on, you have to register them with the Social Security Office (SSO) and file and pay contributions every month; late filing carries a late-payment liability. It is a fixed monthly action, the same as tax filing.
How is sending staff over from China different from hiring locally?
Foreign employees need a work permit and a visa, and are subject to quota and qualification conditions; projects promoted by the Board of Investment (BOI) have a separate channel of their own. Plan headcount together with the company's status — do not wait until people have landed to start the paperwork.
Is a Chinese-language employment contract good enough?
The contract has to be enforceable in Thailand, so use Thai or English as the governing text and make sure it meets the mandatory provisions of Thai labour law. Copying a template used back home is a common source of trouble.
Do Thai employees have to sign a written employment contract?
The law does not require it — an oral employment relationship is protected by Thai labour law just the same — but we strongly recommend a written contract. In a real dispute, leaving pay, position and term to what each side says was agreed puts you in a weak position; once you employ 10 people there are further statutory document obligations, including written work rules in Thai. Putting it in writing is the floor. Individual arrangements can be checked with our consulting team.
Can we sign the employment contract in Chinese only?
You can, but we do not recommend Chinese only. Thai law does not require the employment contract itself to be in Thai, and a Chinese contract is not void simply because of its language. But a dispute goes to the Labour Court, the proceedings run in Thai, and any non-Thai document has to be accompanied by a certified Thai translation — there is a real risk of key wording shifting in translation. Use a Chinese-Thai bilingual contract, state which text prevails, and check the individual case with our consulting team.
If a fixed-term contract simply expires and is not renewed, is severance still payable?
In most cases yes. Letting a contract expire without renewal has the same effect in Thai law as a dismissal, and 120 days of service is enough to trigger statutory severance. The fixed-term contracts that escape it have to meet very tight conditions: a specific project, or temporary or seasonal work, outside the employer's ordinary business; a total term of no more than two years; and a written contract stating the end date from the outset with no extension clause — all of them, not some. If you are counting on short contracts to avoid severance, check the specific case with our consulting team first.
Do non-compete clauses hold up in Thailand?
They do, but only within reasonable limits. The Thai Labour Court reviews them case by case against a fairness and reasonableness standard: the duration, the geographic area and the range of restricted business must match the trade secrets and duties the employee actually had access to. A blanket ban on joining a competitor generally does not survive, and the court can also reduce an agreed penalty. If you want a clause that will really hold a key employee, tailor it to the position and check it with our consulting team while it is still being drafted.
At what headcount does an annual report to the Ministry of Labour become due?
Employers with 10 or more employees must file an annual employment report with the Department of Labour Protection and Welfare every January. This was changed in recent years from "produce it when a labour inspector asks" to a compulsory annual filing, and a great many Chinese-invested companies miss it entirely — the issue is not the size of the penalty but that they do not know the obligation exists.
What is the Employee Welfare Fund, and is it compulsory?
It is a compulsory contribution introduced in recent years, applying to employers with 10 or more employees, with an exemption where a provident fund or an equivalent welfare scheme is already in place. Contributions and notifications of staff changes both fall due by the 15th of the following month, with penalties accruing monthly for lateness; failing to file the register on time or filing false information can also carry imprisonment and a fine.
We already have a provident fund. Do we still contribute to the Employee Welfare Fund?
An employer with a provident fund or an equivalent welfare scheme in place is exempt. Put the other way round: a company that never set up a provident fund and has not registered for the welfare fund has neither — and that is where the exposure most commonly sits.
We hear the social security contribution base is rising. How?
Both the ceiling and the floor of the contributory wage are being adjusted, and the ceiling rises in phases. These are two parameters in the same set of changes, so it is worth being explicit about whether a discussion is about the minimum base or the maximum — conflating them produces the wrong cost projection. The figures and the phasing are as currently provided by the Social Security Office.
An employee reaches retirement age. Does severance still have to be paid?
Yes. The Thai position is that retirement is treated as termination in every case, triggering statutory severance — whether retirement was agreed between the parties, set by the employer's work rules, or initiated by the employee. Where the employee gives notice of retirement, it takes effect after a fixed period and the employer must pay accordingly.
If we re-engage a retired supervisor, will we have to pay severance again?
Possibly. Where someone is re-employed after retiring and receiving severance, the employer must pay statutory severance again on the new contract, based on the new salary, once the qualifying service threshold is met and the contract ends. There is also case law to note: where someone continues working for the same employer past the agreed retirement age without having received severance, service is treated as continuous and unbroken, and is later calculated over the whole period at the final salary.
Can we avoid severance by moving a long-serving employee to a consultancy arrangement?
What the contract says does not settle it — the court looks at substance. Whether it is genuinely independent contracting turns on the degree of control, integration into the business, exclusivity, supervision and economic dependence. The pattern common in manufacturing — a retired engineer re-engaged to train apprentices — where only the label on the contract has changed and the work is the same, will very likely see the severance obligation revive when the arrangement ends.
Have the maternity and paternity leave rules changed?
They have. The ninth amendment to the Labour Protection Act is in force: both the total days of maternity leave and the portion the employer pays at full wage have increased, and it adds paternity leave for the spouse, together with post-natal childcare leave where the newborn has complications or health risks. Budgeting payroll on the old standard understates the cost. The days and payment proportions are as currently provided by the Ministry of Labour.
How should a non-compete clause be drafted to have a chance of holding?
The Thai labour court applies a reasonableness review across three variables — duration, geographic scope and the range of restricted activity — each of which must match the confidential information and responsibilities the employee actually had. A standard template broadly prohibiting "working for a competitor" rarely survives; broad restrictions imposed on shop-floor roles are readily treated as punitive and not enforced. An excessive liquidated damages figure can also be reduced by the court.
What does the company contribute for workplace injury?
In addition to social security, the employer contributes to the Workmen's Compensation Fund, at a rate set by industry risk classification. When projecting total employment cost, social security, the compensation fund and the welfare fund (or provident fund) all have to be counted together — social security alone understates it.
What are the statutory working hours and overtime rules?
There are both daily and weekly limits, and the weekly total is not relaxed by the fact that certain industries may extend the daily hours — using the daily limit in full does not mean the weekly limit can be used in full as well. Work that is hazardous to health carries lower limits again. Two points are often overlooked: overtime requires the employee's consent and cannot be imposed unilaterally, and there must be at least one rest day per week. Overtime is paid at a multiple, higher on holidays than on ordinary days. The hours and multiples are as currently provided by the Labour Protection Act and the Ministry of Labour.
How much annual leave and sick leave are employees entitled to?
They are different in kind and should not be discussed together. Sick leave is taken as the illness requires, with a cap on the paid days; once absence reaches a certain number of consecutive days the employer may require a medical certificate. Annual leave is separate paid leave arising after a full year of continuous service, and runs alongside sick leave. Injury at work and maternity leave do not count against sick leave. The day counts are as currently provided.
How does the minimum wage work? Our plant is in Chonburi.
The minimum wage is set in bands by province, not as a single national figure. What matters here: Chonburi, Rayong and Chachoengsao — the three EEC provinces — are in the highest band, which is precisely where Chinese-invested plants cluster, so labour cost has to be projected at the top band. When choosing a site, weigh the promotion and EEC privileges against the wage band together rather than looking at the privileges alone. The minimum wage is only the baseline; with overtime, social security and the welfare funds on top, the real cost is higher.
Does the employee handbook have to be filed with the Ministry of Labour?
A common misunderstanding. The requirement is not to file it but to adopt and publish it: an employer reaching the specified headcount must publish work rules within the prescribed period from the date the threshold is reached, keep a copy at the workplace, and make them available to employees in a public place or electronically. In other words, where it gets stamped is not the point — whether employees can actually see it is.
How is an open-ended employment contract lawfully terminated?
Notice follows a fixed rhythm: give written notice on or before a pay date, taking effect on the next pay date. This applies to both parties. Note that this makes the procedure lawful; it does not remove severance, which is triggered separately by length of continuous service. The two should not be conflated.
What are the hard limits on employing young workers and women?
There are clear prohibitions. Anyone below the statutory minimum age may not be employed at all; for a young person above it, overtime and holiday work are prohibited, night hours are generally not permitted, and the employment must be notified to the labour inspection authority. For women, the law lists prohibited types of work, with stricter prohibitions for pregnant employees, and dismissal on grounds of pregnancy is prohibited. These are rigid prohibitions, not matters that can be arranged internally.
Besides contributions, are there deadlines on workplace injury?
Beyond contributing at the industry risk rate, payment to the Workmen's Compensation Fund has a fixed deadline early each year — falling in the same window as the January annual employment report, and both are easily missed at the start of the year. Compensation is banded by severity, with continuing payments where there is loss of an organ, disability or death. Amounts, rates and deadlines are as currently provided by the Ministry of Labour and the Social Security Office.
What should we watch when using dispatched or agency workers?
What gets overlooked is that responsibility does not transfer simply because "they are not our employees". Thai law imposes joint protective requirements on the user of dispatched labour, and in practice classifying people as dispatched does not by itself insulate you from severance and welfare obligations; the assessment still looks at actual control, supervision and economic dependence — the same logic used for consultancy and independent contracting. Check the substantive factors before setting the arrangement up, rather than relying on what the contract is called.
What follows if an employee brings an unfair dismissal claim?
Employment disputes fall within the exclusive jurisdiction of the labour court. Beyond statutory severance, compensation for unfair dismissal may be ordered, on top of any liability for unpaid social security contributions and unpaid overtime. The practical point is evidence: where the grounds, the procedure and the records are incomplete, even a sound reason is hard to sustain. Get the record straight before contemplating dismissal.
