List of Chairs of the National Labor Relations Board
The National Labor Relations Board (NLRB) has five Members, each of whom serves for a five-year term. Terms are staggered so that one Member's term expires each year (although delays in nominations and confirmation, as well as the use of recess appointments, can upset this schedule). Members are nominated by the President of the United States and confirmed by the United States Senate. Traditionally, a majority of the board belongs to the President's political party. The President designates the Chair from one of the existing Members. The Chair serves at the pleasure of the President, and may be demoted without cause or warning at any time.
Labor unions in the United States
Private sector unions are regulated by the National Labor Relations Act (NLRA), passed in 1935 and amended since then. The law is overseen by the National Labor Relations Board (NLRB), an independent federal agency. Public sector unions are regulated partly by federal and partly by state laws. In general they have shown robust growth rates, because wages and working conditions are set through negotiations with elected local and state officials.
