The rally is being organized by the American Federation of Government Employees (AFGE), which represents about 10,000 workers in Philadelphia, including Transportation Security Administration agents, Department of Housing and Urban Development employees, and correctional officers, and the National Treasury Employees Union (NTEU), representing more than 5,000 employees locally. Since the shutdown began on Dec. 22 in a dispute over President Donald Trump’s proposal to build a wall between Mexico and the United States, thousands of federal workers have either been furloughed or are working without pay.
