Refusal to work as protest against wage increase constitutes a serious fault under Polish Labor Code Art. 52 § 1.1. Appeal dismissed.

The Supreme Court dismissed the appeal in a dispute where an employee refused to perform assigned tasks as a protest against a denied wage increase. The lower court found that the refusal, combined with the employee's arrogant behavior and disruption of work order, constituted a serious fault under Article 52 § 1, point 1 of the Labor Code. The court ruled that such motivated refusal is blamable and increases the degree of employee fault, justifying dismissal without notice.
