Definition from Nolo’s Plain-English Law Dictionary
An independent agency created by Congress in 1935 to administer the National Labor Relations Act. The NLRB's purposes are to remedy unfair labor practices by unions or employers, and to hold elections to determine whether a particular group of employees wants to be represented by a particular union. NLRB refers both to the agency as a whole and to five members who sit as a court and issue decisions in labor disputes. These decisions can be appealed to the U.S. Court of Appeals.
