If you are wondering about getting furloughed and whether or not you need to report for work on Friday, March 1, 2013, OPM offers this guidance:
Employees who are scheduled to work on March 1, 2013, should report for work. Under sequestration, agencies would still have funds available after March 1, but the overall funding for the remainder of the fiscal year would be reduced. This means that agencies will not be executing any immediate personnel actions, such as furloughs, on March 1. If furloughs or other personnel actions prove to be necessary, agencies will provide affected employees the requisite advance notice.
So yes, you should plan to report to work on Friday.
