Revision dismissing labor appeal; costs allocated to plaintiff despite annulment of prior judgment

The Federal Labour Court reversed the lower appellate court and dismissed the plaintiff's appeal, thereby upholding the first-instance judgment in which the plaintiff had initially failed. The dispute concerned a labor law matter where the plaintiff challenged a decision made by the defendant, resulting in the plaintiff bearing the costs of both the appellate and revision proceedings. The court's decision relied on the definitive application of relevant labor law doctrines to resolve the contested issue, establishing that the plaintiff's claims were without merit under the prevailing legal standards.
