The union representing the largest share of US government workers called for Congress to pass a short-term funding bill to reopen the government, as hundreds of thousands of federal employees are forced to stay home without pay due to the ongoing shutdown.
American Federation of Government Employees National President Everett Kelley urged Congress to pass a clean continuing resolution, which would extend the previous funding agreement with no changes.
"No half measures, and no gamesmanship. Put every single federal worker back on the job with full back pay - today," Mr Kelley said.
The shutdown entered its 27th day on Monday, with no sign of an imminent deal between Democrats and Republicans.
The stalemate has taken a financial toll on federal employees. Those under furlough cannot work and do not receive paycheques while the government is at a standstill. Others deemed "essential" employees must report to work while temporarily forgoing pay.
