Although the Supreme Court upheld the finality of arbitration in contract
disputes, and the NLRB allowed arbitrators to decide cases simultaneously alleging violations of federal labor relations law and the contract,
there are limits on deferral. Individual rights granted under other statutory employment laws cannot be decided in a collectively bargained arbitral procedure if a party objects to the outcome. Thus, if the grievant is dissatisfied with an arbitrator's ruling, the case could be started again by complaining to the appropriate federal compliance agency.
