Validity of disciplinary dismissal and social justification under German labor protection law

The Federal Labour Court dismissed the plaintiff's revision, thereby upholding the lower court’s judgment and leaving the employer prevailing in the dispute over the validity of a disciplinary discharge. The case centered on an employment law dispute where the plaintiff challenged the termination of their employment relationship, with the core issue being whether the dismissal met the requirements of social justification under German labor law. The decisive legal basis involved the proportionality review of the dismissal and the assessment of the operational necessity and employee's conduct under the German Protection Against Dismissal Act, concluding that the employer's actions were lawful and the dismissal was socially justified.
