Failure to perform duties does not justify other employees' breach of obligations in labor dispute.

The Supreme Court dismissed the plaintiff's cassation appeal regarding her termination without notice and claims for compensation. The court found that the plaintiff, a chief accountant, had knowingly neglected her supervisory duties over subordinates and financial documentation for years, causing significant damage to the housing cooperative. Consequently, the court ruled that her own breach of professional obligations did not justify the employer's lawful termination or the alleged violation of social coexistence principles by the employer.
