Allen-Bradley Company v. Local Union #3 325 U.S. 797 (1945)
ALLEN-BRADLEY COMPANY v. LOCAL UNION #3 325 U.S. 797 (1945)
An 8–1 Supreme Court, dominated by appointees of franklin d. roosevelt, held here that union actions that prompted nonlabor market control and business profits violated the sherman antitrust act. The union had obtained closed shop agreements with New York City manufacturers of electrical equipment in return for a promise to strike or boycott any contractor who did not use the local manufacturers' equipment. Because out-of-city materials were cheaper, these agreements effectively restrained competition. Justice hugo l. black, for the Court, found that such action could be enjoined under the Sherman Act because neither the clayton act nor the norrislaguardia act protected union action not solely in its own interests.
