In 1947, the Taft–Hartley Act created a formal administrative distinction between the Board and the General Counsel of the NLRB. In broad terms, the General Counsel is responsible for investigating and prosecuting unfair labor practice claims and for the general supervision of the NLRB field offices. The General Counsel is appointed by the President to a four-year term and independent from the Board; it has limited independence to argue for a change in the law in presenting cases to the Board. The General Counsel oversees four divisions: the Division of Operations Management, the Division of Administration, the Division of Advice, and the Division of Enforcement Litigation.
