Supervisors can send employees on outstanding leave
The employer’s right to grant outstanding annual leave without the employee’s consent and disregarding the scheduled leaves was explicitly provided for in the act on special measures relating to the prevention, counteracting and combatting COVID-19. Employers still have the possibility to send an employee on unused leave (also longer than 30 days). The employee is obliged to take this leave.- Karolina Kanclerz and Łukasz Marzec comment for Rzeczpospolita.
