Probation in Thailand: handling an unsuccessful assessment

Can an employee simply be dismissed for failing probation?

An unsuccessful probation assessment does not remove termination procedures. Employers should deal with the performance assessment and the ending of employment separately. The start date, contract and payroll cycle help determine notice, final pay and other amounts due. Assessment records explain the factual basis for the decision.

What records should the employer retain?

Assessment criteria, feedback, job training and improvement records help explain the basis for the decision. THAIHOUSING can use these materials to organise termination steps and settlement items, distinguishing notice, severance and potential employment disputes.

Does extending probation restart the period already worked?

An extension should not erase earlier continuous service. Ministry of Labour guidance emphasises actual continuous employment rather than a fresh start under each probation document. Keep the original start date and all extension records. Notice, settlement and severance at termination should be assessed against the full employment history.
