Earl Warren,
Guss v. Utah Labor Relations Board…
“ It is hard to imagine that Congress meant to make the proviso the exclusive channel for state jurisdiction when so many States would be automatically excluded from using it. The full mission of the proviso was to supply the National Board with express authority to cede jurisdiction over labor disputes by agreement where, as a matter of deliberate judgment, it concluded that due regard for local interests made that course desirable. The Board's jurisdictional yardsticks always have reflected its need to distribute its limited resources so as best to effectuate the policies of the Act. ”
