The Statute establishes distinct components within the FLRA, including the Authority, the General Counsel of the Authority, and the Federal Service Impasses Panel. Presidential appointees are included in each of these three components. The FLRA structure also includes an Office of Administrative Law Judges.  The FLRA components exercise statutorily independent prosecutorial and adjudicative responsibilities, with different and separate legal roles. The Statute, however, requires the President to designate one of the Authority Members to serve also as the FLRA Chairman, the head of the agency. As the FLRA's chief executive and administrative officer, the FLRA Chairman is responsible for decisions regarding agency-wide administrative functions, such as purchasing, human resources, budgeting, finance, information technology, leasing of office space, and agency performance management. The Chairman carries out these duties through the Office of the Executive Director. The immediate staffs of  Authority Members, the General Counsel, and the Federal Service Impasses Panel (Panel) are under the general, day-to-day supervision of their respective members or component heads. In addition, the Authority Members appoints Administrative Law Judges (ALJs) to hear and prepare decisions in cases involving alleged unfair labor practices, as well as decisions involving applications for attorney fees filed pursuant to the Back Pay Act or the Equal Access to Justice Act. The FLRA also provides full staff support to two other organizations - - the Foreign Service Impasse Disputes Panel and the Foreign Service Labor Relations Board. [created by the Foreign Service Act of 1980] The Authority, General Counsel, and Panel maintain their respective headquarters offices at a common site in Washington, DC. The FLRA Office of the General Counsel also includes staff in regional offices (Atlanta, Boston, Chicago, Denver, San Francisco, Washington DC) and one satellite office (Brea, CA).
