Eastern Thailand — Rayong
Employment & Labour Law in Rayong
Advising employers and employees under the Labour Protection Act.
Why Rayong matters are different
Rayong hosts one of Thailand’s largest petrochemical and manufacturing bases and sits within the Eastern Economic Corridor. Legal work centres on contracts between manufacturers and contractors, employment of both permanent staff and subcontracted labour, promoted-investment conditions, permitting and administrative challenges, and documentation for foreign executives posted locally.
Most labour disputes begin with incomplete paperwork: employment contracts that leave key terms unstated, work rules that were never updated, or terminations carried out without the statutory steps. We advise and litigate in the Labour Court for both employers and employees — from drafting employment contracts and work rules through to mediation and claims for severance pay and unfair dismissal.
- Industrial contracts typically include safety standards and third-party liability terms that must align with occupational safety law.
- Promoted projects carry employment and shareholding conditions, so any restructuring should be checked against the granted privileges before it proceeds.
- Environmental and land-use permits follow specific procedures, and agency orders can be challenged only within limited deadlines.
- Much of the workforce is engaged through subcontractors, so joint liability of the principal arises frequently when wages go unpaid.

Points to watch
- Terminating without stating the reason in writing can prevent the employer from relying on that reason later.

- Overly broad non-compete clauses may be narrowed by the court.
- Outcomes depend on the evidence and the court’s discretion; we do not guarantee results.
Typical timeframe
Mediated labour disputes can conclude within weeks, while cases that proceed to hearing follow the Labour Court’s calendar and the number of witnesses, typically measured in months.

Example situations and how they are handled — Rayong
These are constructed examples used to explain procedure. They are not client matters, and no outcome is implied or guaranteed.
Illustrative scenario: dismissal for underperformance
Situation: An employer dismisses for performance without any warnings or improvement plan on file.
Usual approach: The key is documentation: measurable criteria, warnings and a chance to improve. Without them, dismissal is commonly treated as unfair with severance exposure. (Hypothetical.)
Advice for your specific situation — Rayong
Employees
- Request a dismissal letter stating reasons and date — later-added reasons are hard to rely on.
- Labour claims have filing deadlines — seek advice immediately after dismissal.
Employers
- Keep work rules current and properly communicated — this matters in disputes.
- Calculate severance by service length before giving notice to reduce litigation risk.
Every matter — what to do in the first 7 days
- Gather every original document in one place, keep scanned copies, and note the date you received each one.
- Write a dated timeline — the date you received a notice or learned of the event usually starts the limitation or appeal clock.
- Do not sign a settlement, debt acknowledgement or withdrawal before a lawyer reviews it — it may extinguish existing rights.
- Preserve digital evidence unaltered (full screenshots, original files, emails with headers) — edited files are easy to challenge.
Questions people in Rayong ask
A subcontractor fails to pay wages — is the principal liable?
Labour protection law can make the principal jointly liable with a subcontractor for wages and statutory payments in certain cases. The practical safeguard is a contractual requirement to show proof of wage payment before each instalment is released, with records of those checks kept every period.
A state agency has ordered operations to stop — what options exist?
First check whether the order states its reasons and appeal rights, since administrative procedure law requires reasons. Then note the internal appeal deadline and the deadline for filing in the Administrative Court — missing them forfeits the right even where the substance is arguable.
A foreign executive is posted to Rayong — what documentation is required?
Three elements must align: work authorisation under foreign-worker law, the extension of stay under immigration law, and the employment terms in the contract and any investment-promotion conditions. All three must state the same position and workplace, or renewal filings will be sent back for correction.
When is an employee entitled to severance pay?
Generally when the employer terminates and the employee has not committed one of the statutory disqualifying acts. The rate depends on length of service under the Labour Protection Act; resignation generally does not attract severance.
Must an employment contract be in writing?
The law does not require every employment contract to be in writing, but in practice clear documentation substantially reduces disputes, particularly over wages, position and termination conditions.
What must a foreign employer do to hire Thai staff?
Register as an employer with the Social Security Office, withhold tax from employees’ income, and comply with the Labour Protection Act on the same terms as a Thai employer.
