A cashier must reprimand clients without masks

Employees not only have the right, but also the obligation to discipline clients who are not wearing masks.  This is due to art. 207 par. 1 of the Labor Code, which states that employer is obliged to care about the health and safety in the workplace, and art. 211 point 7 of the Labor Code, which requires the employee to cooperate with the employer and with the superiors in executing it.  – Bartosz Wszeborowski comments for Dziennik Gazeta Prawna.
