Furloughs begin this week for about 680,000 Pentagon civilian employees as part of the Defense Department’s efforts to meet budget constraints.

Despite being exempted, Secretary of Defense Chuck Hagel will also chip in: Pentagon spokesman George Little says that Hagel will make good on his promise to cut his own paycheck in solidarity with furloughed workers.

Little himself will be subject to the unpaid leave, which involves one furlough day each week over the next 11 weeks. He told the Washington Examiner that Friday will be his first furlough day. And in case you were wondering: The 65 non-exempt employees working in the Secretary of Defense’s office of public affairs will switch off Monday and Friday furlough days to keep the office running.

Furloughs will begin to affect paychecks July 19 and are expected to save at least $1.8 billion.
