Labor dispute over employee rights; rejection of revision affirming lower court’s judgment on merits.

The Federal Labor Court (BAG) rejected the plaintiff's revision, upholding the Landesarbeitsgericht's judgment and ordering the plaintiff to bear the revision costs. The dispute concerned a labor law matter where the plaintiff challenged a lower court's decision on specific employment rights or obligations, though the specific subject matter is not detailed in the provided text. The court's decision rests on the procedural outcome that the plaintiff failed to demonstrate a reversible error in the application of labor law, thereby affirming the validity of the prior instance's ruling.
