Attempted theft of employer property constitutes a serious breach of employee duties under Polish Labor Code.

The Supreme Court dismissed the cassation appeal filed by two drivers seeking reinstatement after their employer terminated their contracts. The court found that the drivers conspired to manipulate vehicle weight on a scale to steal approximately 60 liters of rectified spirit from the employer. Consequently, the court ruled that this joint action constituted a serious breach of fundamental employee duties under Article 52 of the Labor Code, justifying the termination.
