Kaynard v. Metallic Lathers & Reinforced Concrete Steel Workers Union
The acting regional director of the National Labor Relations Board sought a temporary injunction against Local 46, Wood, Wire & Metal Lathers International Union, AFL-CIO. The NLRB alleged the union unlawfully picketed Prefabricated Concrete, Inc., to compel the assignment of metal work to its members rather than to employees represented by a certified union, Local 3127. Despite the union's claim of informational picketing regarding wages, the court found reasonable cause that the picketing's true object was an unlawful work assignment dispute under the National Labor Relations Act. The picketing severely disrupted concrete deliveries to Prefabricated. The petition for the temporary injunction was granted, restraining the union from picketing during business hours.
