The Department of Defense has notified congress 800,000 civilian employees might have to be furloughed.
The move is a part of the sequester that could bring $46-billion in across the board cuts on March 1st.
There are almost 5,000 civilian defense employees on the Rock Island Arsenal, according to a spokesperson. The union that represents the employees say there are 8,000.
Arsenal and union officials do not know how many local civilian employees would be put on unpaid leave.
What they do know is employees would have one day a week of forced leave for 22 weeks, which means they will lose 20% of their pay.
"The Rock Island Arsenal impacts the community by about 18%, 19%, 20% cut 20% of your spending capacity out of that," American Federation of Government Employees Local 2119 Craig Flenker said. "It will work it's way through the whole economy, you just can't avoid it."
The Defense Department will start to issue letters in the middle of March.
The letters will give civilian employees 30 days notice that the furloughs will start at the end of April. The 22-week furlough will go until the end of September.
