National Labor Relations Board (NLRB)

The federal agency that enforces the National Labor Relations Act, conducts union elections, and investigates unfair labor practices.

Full definition

The National Labor Relations Board (NLRB) is the independent federal agency created by the National Labor Relations Act (NLRA) of 1935 to enforce private-sector labor law in the United States. The NLRB has two principal functions: (1) conducting secret-ballot elections to determine whether employees wish to be represented by a union, and (2) investigating and prosecuting unfair labor practice (ULP) charges filed by employees, unions, or employers. The Board operates through regional offices around the country and is led by a five-member Board appointed by the President. The NLRB does not have jurisdiction over public-sector employees, who are covered by state public employment relations boards, or over certain workers excluded from the NLRA such as agricultural and domestic workers.
