Labor dispute over employer’s action: employee’s claim for relief rejected after lower court’s partial reversal

The Federal Labour Court (BAG) dismissed the claimant’s revision, partially reversing the appellate ruling and upholding the lower court’s judgment to reject the action, thereby leaving the defendant’s position intact and assigning the costs of the litigation to the claimant. The dispute involved a challenge to a measure taken by the employer, reviewed through a three-tier procedure where the appellate court had partially in favor of the employee, while the BAG overturned this partial success. The decisive legal basis rests on the BAG’s interpretation of the applicable labor law provisions governing the validity of the contested employer action, establishing that the claimant failed to demonstrate the requisite legal grounds for relief against the defendant.
