Polish Supreme Court dismissed most appeal but allowed reinstatement claim due to serious employee duty breach.

The Supreme Court of Poland partially dismissed the appeal, rejecting the employer's claim that the employee's letter constituted a serious breach of duty while ordering the reinstatement claim to be remanded. The court found that unsubstantiated accusations of serious crimes against the company president, including bribery and tax evasion, violated the employee's duty of care and good faith. Although the employer argued the letter was merely private correspondence, the court held that presenting such grave unproven allegations to management justified termination without notice.
