Houston Insulation Contractors Ass'n v. National Labor Relations Board

Background

A group of insulation contractors and two local union chapters disputed who must do certain cutting and fitting work on construction jobs. One union local had a contract clause reserving cutting work for its members. On two job sites, employers bought pre-cut bands or fittings from outside manufacturers, and union agents instructed members not to install those pre-cut items to preserve the contracted work.

Reasoning

The Court considered whether those refusals were protected activity or unlawful secondary boycotts under the National Labor Relations Act. The Board found the unions’ conduct aimed to preserve work customarily done by the employer’s own employees and treated it as primary activity protected by the Act. The Court agreed that when union members act to influence their own employer to protect jobs promised by a contract, that is protected primary concerted activity and not a secondary boycott—even if a sister local or only some employees take the action.

Real world impact

The ruling means unions can sometimes lawfully refuse to install pre-cut materials or join short solidarity actions to keep work for their members, without automatically being treated as illegal pressure on a neutral employer. One Board ruling was affirmed and another Court of Appeals ruling was reversed, so the immediate outcome varies by case, and some disputes may still be decided differently on the facts.

Dissents or concurrances

Four Justices dissented in related opinions, expressing disagreement with the Court’s treatment of these solidarity actions, but the majority’s view controls here.
