Employment termination protection: proportionality of dismissal and employer’s justification grounds

The Federal Labor Court (10th Senate) reversed the Higher Regional Labor Court and dismissed the employee's claim, resulting in the employer's full victory; the court upheld the first-instance decision's abrogation of the lower court's judgment, ordering the employee to bear 7/8 of the litigation costs. The dispute concerned a termination protection suit challenging the validity of an employment contract termination, where the employee contested the dismissal's proportionality or procedural legality. The decisive legal basis centered on the criteria for lawful termination under German labor law, specifically assessing whether the employer's operational or personal grounds provided sufficient justification to override the employee's continued claim to the position, leading to the conclusion that the termination was lawful and the employee's claims unfounded.
