The notice period for the termination of all kinds of employment contracts (permanent, fixed-term, for probationary period) depends on the employee’s length of service with the employer. 

A two-weeks notice period is required if the employee has been employed for fewer than six months, and one month notice period is required if the employee has been employed for at least six months. If the employee has been employed for at least three years, a three-months notice period should be given.

The probationary contract can be concluded for a maximum of 3 months. With the same employee, another probationary contract can be signed only:

• if it concerns a different workplace,
• after 3 years.

The probationary contract may be terminated and the period of notice is

• 3 working days if the probationary period does not exceed 2 weeks;
• 1 week if the the probationary period is longer than two weeks;
• 2 weeks if the probationary period is 3 months.

During collective dismissal notice period is the same. Notice period can be extended in the labour contract or collective agreement but in an asymmetric way what means it can be extended only for situations when the contract is terminated by the employer, not by the employee.
