If the government were to shutdown due to Congress not passing a spending bill next week, 41 percent of the federal government's workforce will shutdown as well, according to USA Today.
59 percent of the non-defense workforce will be exempt from the shutdown, according to the Federal Daily.
These numbers come from an analysis of 119 contingency plans submitted to the Office of Management and Budget.
The agencies that are exempt include those that don't run on annual appropriations from Congress such as the Postal Service, the Patent and Trademark Office and the Federal Highway Administration.
Other parts of the government that are exempt include political appointees, law enforcement, most overseas foreign service officers and those deemed necessary for health or safety of people or property.
The report also said that most federal workers will work a half day at the beginning and end of a shutdown.
