Oil, Chemical & Atomic Workers International Union v. Mobil Oil Corp.

Background

A union representing 289 unlicensed seamen and their employer, a Mobil Oil shipping division headquartered in Beaumont, Texas, signed a collective-bargaining deal that included an agency-shop rule requiring workers to pay union fees. Most hiring decisions and personnel records were handled in Beaumont, but the seamen spent about 80–90% of their work time on the high seas. The employer sued, asking a federal court to declare the agency-shop clause void under Texas’ right-to-work statutes.

Reasoning

The Supreme Court examined the question of which location counts when a State tries to apply its right-to-work law to a multistate employment relationship. The Court held that Congress intended the decisive factor to be the employees’ predominant job situs — the place where they actually do most of their work — because the federal rules governing agency- and union-shop arrangements focus on conditions that apply after hiring, while §14(b) lets States block such post-hiring requirements where those requirements are performed within the State. Because these seamen did most of their work outside Texas (on the high seas), Texas’ right-to-work law could not void the agency-shop clause.

Real world impact

As a result, employer–union agreements that require fee payments can stand for maritime crews who perform most work off-state shores, even if hiring or paperwork occurred in a State that bans such agreements. The ruling promotes a predictable rule — look to where work is mainly done — for unions and employers bargaining over union-security terms.

Dissents or concurrances

Some Justices would have used different tests. One dissent favored treating the place of hiring as controlling; another concurrence stressed maritime workers’ special federal status.
