A federal appeals court has upheld a lower court’s ruling that an arbitrator handling a labor dispute between a union employee and a hospital over vacation time overstepped his authority.

On Dec. 30, the U.S. Court of Appeals for the Third Circuit upheld the trial court’s grant of summary judgment in favor of Monongahela Valley Hospital, vacating an arbitration award in favor of United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers International Union, AFL-CIO, CLC.
