Supreme Court dismissed appeal; collective agreement not labor law source or third-party performance contract.

The Supreme Court dismissed the cassation appeal against a lower court ruling that rejected the plaintiff's claim for compensation. The plaintiff, a former manager, sought damages based on a collective agreement between trade unions and a strategic investor, arguing it functioned as a source of labor law or a contract for third-party performance. The court held that the agreement was merely a source of mutual obligations between the signatories and did not create direct rights for employees against the employer, nor did it constitute a labor law source or a third-party performance contract under the cited statutes.
