Drunk arrival at work site without readiness to work constitutes serious breach of duties under Polish Labor Code.

The Supreme Court dismissed the employee's cassation appeal regarding his dismissal for failing to report to work while intoxicated. The court held that mere physical presence at the workplace does not satisfy the obligation to be ready to perform duties, especially when intoxication prevents actual work. Consequently, the employer's decision to terminate the contract without notice was upheld as a valid response to a serious breach of employee obligations.
