The National Labor Relations Board was established in 1935 to administer the National Labor Relations Act, which is a primary law that governs relations between unions, employees and employers in the private sector. The board works to prevent and rectify unfair labor practices and ensures labor organization representation for unions for collective bargaining purposes. It is governed by a five-member board and General Counsel, all of whom are appointed by the president with the consent of the senate. The General Counsel acts as a prosecutor and the board acts as an appellate judicial body from decisions of administrative law judges. The National Labor Relations Board s jurisdiction is limited to private sector employers and the U.S. Postal Service.
