William J. Brennan, Jr., Sinclair Refining Company v. Atkinson…
“ The decision deals a crippling blow to the cause of grievance arbitration itself. Arbitration is so highly regarded as a proved technique for industrial peace that even the Norris-LaGuardia Act fosters its use. [22] But since unions cannot be enjoined by a federal court from striking in open defiance of their undertakings to arbitrate, employers will pause long before committing themselves to obligations enforceable against them but not against their unions. The Court does not deny the desirability, indeed, necessity, for injunctive relief against a strike over an arbitrable grievance. ”
