I had heard this too... anyone here part of those furloughs in the past that can comment? I heard someone who had gone through it before on the radio comment that she just laughs because she knows it will end up being a paid vacation is all.
I doubt it will happen this time.
In the past those furloughs were a result of budget arguments, the failure to pass authorizations, and government shutdowns etc...once the issue was resolved and the money/budget/authorizations were worked out, then folks got paid.
These furloughs are a result of the requirement to stop spending money. Turning around later and authorizing back pay for time not worked then erases any spending cuts or savings....making it pointless.
Then again, because it would be pointless, it'll probably happen that way. LOL.
