The American Federation of Government Employees (AFGE) is an American labor union representing over 670,000 employees of the federal government, about 5,000 employees of the District of Columbia, and a few hundred private sector employees, mostly in and around federal facilities. AFGE is the largest union for civilian, non-postal federal employees and the largest union for District of Columbia employees who report directly to the mayor (i.e., outside D.C. public schools). It is affiliated with the AFL–CIO.
