Validity of termination agreement in employment dispute: requirements for effective waiver of claims

The Federal Labor Court reversed the lower appellate court's decision and dismissed the plaintiff's claim, resulting in a final victory for the defendant and an award of litigation costs to the plaintiff. The dispute concerned a termination of employment agreement, specifically challenging the validity or consequences of the agreed-upon dismissal. The court determined that the plaintiff’s claims were unfounded under the applicable provisions of the German Labor Court Act and the Civil Code governing termination agreements, leading to the complete abrogation of the favorable ruling obtained in the appellate instance.
