I don’t see how you’re worried about being pay. Your contract is funded at appropriation until its expiration or renewal. Your’s must be a very short term or general funds contract. Our’s is funded on a yearly basis and our current year just started.
Ours is also yearly. However, as a contractor, you know you cannot bill for hours you do not work. Period. So, because of the shutdown, I am not allowed on the property and I am forbidden from accessing Federal assets (such as Citrix servers to remotely-work).
I suppose I could work an extra hour every day upon return, and make the missed money up in that fashion.
But if it goes on too long, I will be reporting to a new, private sector job.
