National Labor Relations Board

The National Labor Relations Board (NLRB) is an independent agency of the federal government of the United States that enforces U.S. labor law in relation to collective bargaining and unfair labor practices. Under the National Labor Relations Act of 1935, the NLRB has the authority to supervise elections for labor union representation and to investigate and remedy unfair labor practices. Unfair labor practices may involve union-related situations or instances of protected concerted activity.
