Supreme Court dismissed cassation, ruling insulting behavior constitutes a serious breach of duties under Art. 52 § 1 k.p.

The Supreme Court dismissed the employee's cassation appeal against a labor court decision terminating her contract without notice. The lower courts found that while the employee's behavior was inappropriate, the first instance incorrectly failed to classify her insulting conduct as a serious breach of duties under Article 52 § 1 of the Labor Code. The Supreme Court held that such behavior, involving vulgar language and humiliation, demonstrated intentional fault and violated the employee's duty to observe social coexistence and diligence, thereby justifying immediate termination.
