Byron White, Vaca v. Sipes — Opinion of the Court
“ We cannot believe that Congress, in conferring upon employers and unions the power to establish exclusive grievance procedures, intended to confer upon unions such unlimited discretion to deprive injured employees of all remedies for breach of contract. Nor do we think that Congress intended to shield employers from the natural consequences of their breaches of bargaining agreements by wrongful union conduct in the enforcement of such agreements. ”
