The limits of the employee privilege

Only if the parties have expressly stipulated in the employment contract that the compensation will be due in the amount of the remuneration for the extended period of notice, the employee is entitled to compensation in a higher amount than provided for in Article 47[1] of the Labour Code. If the parties, while extending the period of notice, have not agreed on compensation in an amount corresponding to this extended period, the employee may only claim compensation in the amount of the statutory maximum three-month remuneration. – Mariusz Maksis comments for Rzeczpospolita.
