Validity of collective agreement provisions challenged by employee

The Federal Labour Court (BAG) dismissed the plaintiff’s revision appeal, upholding the Landesarbeitsgericht Baden-Württemberg judgment and leaving the defendant prevailing; the costs of the proceedings were borne by the plaintiff. The case concerned a dispute over the enforcement of collective bargaining agreement provisions, specifically regarding a contractual entitlement or benefit challenged by the employee against the employer. The court’s decision relied on the interpretation and application of the relevant collective agreement clauses under German labour law, determining that the lower court’s assessment of the legal effect of these provisions was correct and that the plaintiff’s claim lacked the necessary legal basis.
