William E. Arnold Co. v. Carpenters District Council

Background

An employer, William E. Arnold Co., sued a local carpenters’ union after the union struck to force reassignment of work claimed by its members. The employer asked a state trial court to stop the strike by enforcing a no-strike clause in the parties’ collective-bargaining agreement. The Florida Supreme Court said the state court could not act when the strike might also be an unfair labor practice under federal law, and it barred the state court from issuing an injunction.

Reasoning

The Supreme Court reversed the Florida decision. It explained that when a dispute is really about enforcing a collective-bargaining agreement under federal law section 301, state courts may hear the case. The Court relied on prior decisions and on the National Labor Relations Board’s practice of deferring to contractual dispute procedures. The opinion noted federal law encourages parties to use agreed grievance and no-strike mechanisms, and a special federal procedure for jurisdictional fights supports voluntary settlement. The Court also said the type of relief sought—an injunction to stop an ongoing strike—is appropriate in state courts and not limited to money damages in federal court.

Real world impact

The ruling means employers can seek immediate state-court orders to stop strikes that violate no-strike clauses, even if unions argue federal labor law also applies. It reinforces the importance of contract grievance systems and may encourage parties to use agreed procedures rather than walk off the job. The Court did not decide whether any particular injunction should be granted; that question goes back to the lower courts for further proceedings.
