Employment lawsuit dismissed as inadmissible for insufficient specification of the claim

The Federal Labor Court reversed the appellate decision and dismissed the plaintiff's claim as inadmissible, thereby upholding the defendant's position and ordering the plaintiff to bear the litigation costs. The dispute concerned the validity of a lawsuit filed by an employee against an employer, where the lower court had previously ruled in the plaintiff's favor. The decisive legal basis was the requirement that a claim must be clearly and sufficiently specified at the time of filing; the court held that the plaintiff failed to meet this admissibility threshold, rendering the substantive merits of the case moot and the claim legally unenforceable in its current form.
