A partial government shutdown could go into effect at midnight on Dec. 21, forcing thousands of federal workers to be placed on unpaid leave until a funding deal is brokered.

The shutdown would affect specific government departments, including the Department of Homeland Security, which provides border security, as well as the “departments of Agriculture, Commerce, Justice, Interior, State, Transportation and Housing and Urban Development,” according to Fox Business. 

Funding for the Department of Defense was passed earlier in the year, eliminating the concern of military troops serving without pay, aside from the Coast Guard, which is funded through DHS.
