In the landmark case National Labor Relations Board v. Jones & Laughlin Steel Corp., the U.S. Supreme Court upholds the ruling that the National Labor Relations Act of 1935 is constitutional and that labor-management disputes are within the authority of the commerce clause. The NLRB brings charges against Jones & Laughlin Steel Corp. for discriminating against labor union members and prospective members in hiring and for firing a number of union members in violation of the act. The Court grants certiorari to the District Court ruling against Jones & Laughlin Steel Corp. on the grounds that labor-management relations indirectly but significantly affect interstate commerce.
