You may agree a trial period with your employer when you begin working. This trial period may not be longer than six months, and it may not be longer than half of the agreed employment period in a temporary job. The employer can prolong a trial period if the employee has been incapacitated or on family leave for 30 calendar days or more during the trial period.
The trial period must be explicitly agreed in the employment contract, even when the collective agreement provides for trial periods. Your employer must also inform you that there is a trial period when making the employment contract.
Both the employer and the employee may terminate the employment contract with immediate effect during a trial period, but not on grounds that are improper or discriminatory, such as a brief period of illness or because the employee is pregnant. There is no period of notice when an employment contract is terminated in this way during a trial period.
If a client enterprise hires an agency worker directly after a period of agency work performing the same or similar duties for that enterprise, then this period must be deducted from the maximum length of any trial period.
