The probation period is the period at the beginning of the employment during which the employee is “on trial”, meaning that he/she is being assessed to determine whether the contract will become permanent. In general, during the probation period, it is easier to dismiss an employee because either a shorter notice period applies, or the dismissal does not need to be motivated. In almost all countries it is allowed to include probationary periods in the employment contracts. The exceptions are Belgium and Chile, where probation periods are not allowed by law. Thai labor law is silent on probation periods, but in practice, parties can agree to put it in place. The maximum term of the probation period often depends on the job level. The higher the rank, the longer the probation period can be. In France for example, the maximum probation period is two months for office workers, but four months for executives.
