Texas State Tile & Terrazzo Co., Inc., et al. v. Plasterers' Local Union No. 79, Operative Plasterers' & Cement Masons' International Assn., AFL-CIO, et al.

Opinion summary

Etalia.ai summary of the majority opinion

The case involved a dispute between Texas State Tile & Terrazzo Co., Inc. and other contractors, against Plasterers' Local Union No. 79 and its parent organization, the Operative Plasterers' & Cement Masons' International Association, AFL-CIO. The central issue was whether certain actions by the union constituted unfair labor practices under the National Labor Relations Act (NLRA). Specifically, it examined if picketing activities aimed at coercing neutral employers to cease doing business with non-union subcontractors violated Section 8(b)(4) of the NLRA. The Supreme Court held that such secondary boycotts were indeed prohibited by federal law as they exerted improper pressure on neutral parties not directly involved in a labor dispute with the unionized entity.
