Until the end of 2013, Belgian employment law allowed parties to include a probation clause in the employment contract. The probation clause enabled both parties to assess the employment relationship during a predetermined period and, if necessary, to terminate it quickly with short notice periods.
With the Unity Statute Act, the probationary period and the probationary clause were abolished from 1 January 2014 for employment contracts commencing on or after 1 January 2014.
However, the probationary period remained in place for student work and temporary/agency work. For student work, the first three effective working days automatically count as a probationary period. During these three days, the employer and the student may terminate the contract without notice or compensation. In principle, the first three effective working days also count as a probationary period for contracts for temporary work and agency work, during which the employer and the employee may terminate the contract without notice or compensation.
On 21 May 2026, a draft bill amending the Employment Contracts Act was adopted in the Chamber of Representatives. The new law does not provide for the exact reintroduction of the probationary period, but it does provide for a reduction in the statutory notice periods for employees with less than six months’ seniority. For both employers and employees, the notice period during the first six months of employment will be one week. An overview of the new notice periods follows:
| Seniority | Notice periods prior to the legislative amendment | New notice periods | ||
|---|---|---|---|---|
| Notice by employee | Employer’s notice | Notice by employee | Employer’s notice | |
| < 3 months | 1 week | 1 week | 1 week | 1 week |
| From 3 months to < 4 months | 2 weeks | 2 weeks | 1 week | 1 week |
| From 4 months to < 5 months | 2 weeks | 4 weeks | 1 week | 1 week |
| From 5 months to < 6 months | 2 weeks | 5 weeks | 1 week | 1 week |
| From 6 months to < 9 months | 3 weeks | 6 weeks | 3 weeks | 6 weeks |
The new, shortened notice periods apply only to employment contracts commencing as of 1 August 2026. Consequently, the legislative amendment does not affect existing employment contracts.
From the date of entry into force on 1 August 2026, it is essential to verify whether the employment contract commences before or after the law’s entry in force, as that date determines the applicable notice period. An employee who starts two weeks before the law takes effect will be entitled to a substantially longer notice period during their first six months of employment than a colleague who starts the day after the law enters into force.
