National Woodwork Manufacturers Ass'n v. National Labor Relations Board

1967-04-17

Headline: Court allows union work-preservation clause banning handling of prefitted doors, ruling it did not violate federal hot-cargo and product-boycott bans and letting jobsite carpenters refuse prefitted doors in these circumstances.

Holding: The Court held that a union’s “will not handle” contract clause and enforcement to preserve traditional jobsite carpenters’ work did not violate §8(e) or §8(b)(4)(B) because it was primary, work-preserving activity.

Real World Impact:

Allows unions to refuse to install prefitted, premachined doors on jobsites to preserve carpenters' tasks.
Means contractors may be forced to order blank doors and have carpenters fit them.
Limits product-boycott claims when the objective is preserving work for the employer's own employees.

Summary

Background

A local carpenters’ union had a clause in a regional contractors’ agreement saying members would not handle doors that had been fitted before arriving on the job. A general contractor bought prefitted doors from a manufacturer, and the union ordered its members not to hang them. A trade group for door makers filed charges with the National Labor Relations Board saying the clause and the boycott violated federal bans on “hot cargo” agreements and product boycotts. The Board and a trial examiner found the clause protected traditional jobsite work and dismissed the charges; a federal court later reversed that part of the Board’s decision.

Reasoning

The Supreme Court examined the statutory language and Congress’s history of distinguishing "primary" activity (direct pressure between an employer and its own employees about work) from "secondary" boycotts (pressure on neutral third parties). The Court concluded Congress intended the statutes to stop secondary objectives that coerce neutrals, not to bar agreements or strikes aimed solely at preserving unit work for an employer’s own employees. Because the record showed the clause and the union’s refusal to hang prefitted doors were aimed at protecting traditional jobsite tasks, the Court held they were primary, work-preserving activity and not unlawful under the cited labor provisions.

Real world impact

In practice, the decision permits unions and contractors in similar circumstances to negotiate and enforce clauses preserving traditional on-site tasks and to refuse prefitted materials when the aim is to protect unit work. The Court stressed, however, that different facts showing a tactical effort to pressure neutrals or to monopolize jobs could still be unlawful.

Dissents or concurrances

A dissent argued the statutory text and legislative history clearly reach product boycotts used for work preservation and would have found the clause unlawful. This highlights that reasonable legal disagreement exists about where to draw the line.
