Employment termination dispute; effectiveness of dismissal and appellate review of labor court judgment

The Federal Labor Court reversed the appellate court’s judgment and dismissed the employee’s appeal, thereby upholding the labor court’s initial ruling in favor of the employer and ordering the employee to bear all costs for the appellate and revision proceedings. The case involved a dispute over the termination of employment, where the employee challenged the effectiveness or lawfulness of the dismissal. The decisive legal basis centered on the substantive requirements for a valid termination and the standards of review applied by the higher labor courts in assessing whether the termination met the necessary legal criteria, ultimately finding no grounds to disturb the lower court's determination.
