Supreme Court dismissed claim that same work could be performed simultaneously for two employers.

The Supreme Court dismissed the cassation appeal filed by an employee against her former employer, Tadeusz S., regarding unpaid overtime and termination damages. The employee argued that she worked for the defendant, but lower courts had already established she was employed by a different entity, Przedsiębiorstwo Zagraniczne „A.-D.”, based on final judgments. The court ruled that the same factual work cannot be performed simultaneously for two employers, making it impossible to claim double compensation for the same period.
