Thousands of employees of the government will be faced with undetermined leaves of absences, as it has now been shut down.
President Obama was on hand in the White House briefing room on Monday just hours prior to the deadline.
He promised Americans that federal prison guards and air traffic controllers would remain at work and that they'll also still be receiving their Social Security checks as well as Medicare aid.
However, he also warned that the situation won't exactly be a pretty one, especially for those Federal employees who'll be sent home without any pay until an agreement can be reached on Capitol Hill.
"A shutdown will have a very real economic impact on real people right away," Obama explained.
All federal workers should still go to work on Tuesday and their managers will give out the official notices on who is and isn't needed for daily operations, according to Politico.
"It's a different kettle of fish when you say people aren't going to show up at all," stated a former Clinton administration official that was involved with the last government shutdown in 1995 and 1996.
The site also stated that Federal workers should also be monitoring news sites in order to get updates on when they can return to their jobs.
