When an employment agreement is unilaterally terminated by the employer or employee by giving notice, a notice period must be taken into account. The notice period is related to the years of service of the employee at the time of termination and may extend up to 6 months for the employer and a maximum 3 month notice period applies for the employee giving notice.
The notice period which needs to be taken into account by an employee may be up to a maximum of six months. Extension of the notice period is only possible when parties have agreed to such in writing. The extended notice period for the employee may not be longer than 6 months and the notice period for the employer may not be shorter than twice the length of the extended notice period of the employee. Shortening of the notice period which needs to be taken into account by the employer can only be realized by a Collective Employment Agreement.
