National Labor Relations Act

National Labor Relations Act, or Wagner Act, law enacted in 1935 permitting the establishment of unions to protect employees' rights, and requiring employers to participate in collective bargaining with elected union representatives. The act created the National Labor Relations Board (NLRB) to monitor both the union and the employer to counteract unfair practices by either side. In 1947 the Taft-Hartley Act amended the Wagner Act by limiting union strength.
