Restructuring or Reducing Headcount in Thailand: Planning Redundancies Without Unfair Dismissal Claims

Thai law allows a company to reduce its workforce for genuine business reasons, but the Labour Court looks at why, who was chosen and how. Selection criteria, notice, the special rules when machinery or technology replaces jobs, voluntary separation schemes, and the protected groups to check first.

A lawful reason is not the same as a fair process

Thai law allows a company to reduce its workforce for genuine business reasons — lower demand, closure of a line, a reorganisation, new technology. It is not a disciplinary dismissal, and the employee has done nothing wrong.

That is exactly why the process matters. Because the employee is not at fault, severance and notice are still owed, and if a dismissed employee claims the termination was unfair, the Labour Court examines why the reduction was needed, who was selected, and how the process was run.

1. Document the business reason first

Before any names are discussed, write down:

  • What has changed in the business — volumes, contracts lost, a line closed, a process automated
  • Which roles or units are affected and why
  • What alternatives were considered — reduced hours, redeployment, transfer to an affiliate, relocation

A reason written after the list of names looks like a justification. A reason written first looks like a decision.

See transferring employees to an affiliated company and relocating your workplace for alternatives that follow their own rules.

2. Selection criteria

Use criteria that connect to the business reason and can be applied consistently:

CriterionWhen it works
Role or unit removedThe work itself no longer exists
Skills needed after the changeThe remaining roles need different capabilities
Performance recordsOnly if records exist, were kept consistently and pre-date the decision
Length of serviceAs a tie-breaker, applied the same way to everyone

Record how each criterion was applied to each employee in the affected pool. A spreadsheet prepared at the time is far stronger evidence than a recollection at trial.

3. Protected groups to check before finalising

  • Pregnant employees — dismissal on account of pregnancy is prohibited
  • Employee representatives and committee members — specific protections apply
  • Union members and officials
  • Employees with pending complaints, claims or inspections
  • Employees on leave for sickness, injury or maternity

Selection that falls disproportionately on these groups invites the argument that the redundancy was a pretext.

4. When machinery or technology replaces jobs

A specific rule applies where employees are terminated because the employer reorganises its work, production, distribution or services as a result of introducing or changing machinery or technology:

  • The employer must notify the labour inspector and the affected employees in advance, within the period the law sets
  • If notice is not given, special severance in lieu of notice is payable
  • Employees with long service are entitled to additional special severance on top of ordinary severance

If automation is part of the reason, plan the notice timeline around this rule.

5. Notice and payments

For every employee terminated in the reduction:

  • Notice under the employment terms and the law, or pay in lieu
  • Severance according to length of service — see severance pay in Thailand
  • Accrued entitlements — unused annual leave, outstanding wages, overtime
  • Special severance where the technology rule applies
  • Timely payment — late payment of severance creates further liability

6. Voluntary separation schemes

A voluntary scheme reduces claims because the employee chooses to leave. It works when:

  • Eligibility is clear and applied consistently
  • The choice is genuinely voluntary, with time to decide
  • Terms are at least as good as the legal entitlements, usually better
  • Communication does not imply that those who stay will be dismissed anyway

Releases signed on departure are useful, but a release obtained through pressure is weak. A scheme that is voluntary in form but not in practice is treated as a dismissal.

7. Communication and sequence

  1. Business reason and alternatives documented
  2. Affected pool defined and criteria agreed
  3. Protected-group check completed
  4. Budget approved for severance, notice and any special severance
  5. Notifications prepared where the technology rule applies
  6. Voluntary scheme launched, if used, with a closing date
  7. Individual meetings held, letters delivered, payments made on time
  8. Work permits of departing foreign employees handled
  9. Records kept together in one file

After the reduction

Expect questions from the labour office and, sometimes, claims. A complete file answers them quickly. See defending an employer in the Labour Court.

Frequently asked questions

Can a company in Thailand dismiss employees because business is down?+

Yes, a genuine business reason can justify termination, and it is not a disciplinary dismissal. But severance is still payable according to length of service, notice or pay in lieu is still required, and the Labour Court can find a dismissal unfair if the reason was not genuine or the selection was not fair. The reason, the criteria and the process all need to be documented.

What is different when machinery or technology replaces jobs?+

Where employees are terminated because the employer reorganises its work, production, distribution or services as a result of introducing or changing machinery or technology, the employer must notify the labour inspector and the affected employees in advance within the period the law sets. If it does not, special severance in lieu of notice is payable, and employees with long service are entitled to additional special severance.

How should we choose who goes?+

Use objective criteria connected to the business reason — the role or unit being removed, skills needed after the change, performance records applied consistently, and length of service — and record how each criterion was applied. Selection that looks targeted at particular individuals, or that falls disproportionately on protected groups, is what turns a lawful redundancy into an unfair dismissal claim.

Is a voluntary separation scheme a good idea?+

Often, because an employee who chooses to leave on enhanced terms is much less likely to claim. The scheme needs clear eligibility, a real choice, time to decide, and terms at least as good as the employee's legal entitlements. Releases signed at the point of departure are worth having, but they are not a substitute for a genuinely voluntary process.

Which employees need special care?+

Pregnant employees, whose dismissal on account of pregnancy is prohibited; employee representatives and committee members, who have specific protections; union members; and employees with pending complaints or claims. Check each list before finalising selection.
