Southern Steamship Co. v. National Labor Relations Board

Background

A union sought an election among unlicensed crew on seven vessels. The National Maritime Union won a majority and the Labor Board certified it. The steamship company refused to bargain. While one ship was at dock in Houston in July 1937, a crew strike began to press union demands. Five crewmen were later told they would not be reshipped and other crew members struck in protest. The Board found the company guilty of unfair labor practices and ordered bargaining, reinstatement with back pay, and notices.

Reasoning

The Court examined whether the shipboard strike violated federal criminal statutes against mutiny and revolt on vessels in U.S. navigable waters. The majority concluded the refusal to obey the captain and officers, even without violence, met those statutes because authority aboard ship must be absolute for safety. Because Congress has spoken on discipline at sea, the Court held the Board could not, in effect, override that legislative policy by ordering reinstatement after an unlawful strike. The Court therefore limited the Board’s remedy, reversing reinstatement and back pay but leaving the bargaining and posting orders intact.

Real world impact

Companies must still negotiate with certified unions and post notices, but the Board cannot force rehiring when workers’ conduct falls within mutiny or related criminal prohibitions. Seamen and unions face clear limits on strikes while ships are in navigable U.S. waters, including docks and harbors. Unions and the Board may need to seek court help to enforce bargaining rights without risking criminally prohibited conduct.
