Court dismissed employee's bonus claim due to proven breach of duties causing employer loss.

The court dismissed the plaintiff's claim for a performance bonus totaling over 28,000 PLN, ruling that the employer was entitled to withhold it. The plaintiff argued he earned the bonus for 2011 despite his contract being terminated without notice due to a conflict. The court found that the collective agreement allowed the employer to deny the bonus if the employee breached basic duties or caused damage, which the plaintiff admitted to doing. Consequently, the plaintiff lost the case and was ordered to pay the defendant's legal costs.
