Temporarily furloughing something like 15% of the "non-essential" personnel (why are they there in the first place?), who will eventually be paid in full, isn't any kind of "shutdown"....Bunch of media generated hype, weeping, and wailing is about all this is.
Non essential personnel who are furloughed DON'T get paid for the time they aren't at work. The only people who will get back pay and be paid in full are the essential personnel who remain working, but, those essential personnel won't be paid until the government is reopened.
I know. I went through one for 24 days back in the mid 90's. All military personnel were required to come to work, but we missed a payday during that time and some of the lower ranks who lived paycheck to paycheck and had families had to go to Navy Relief for a loan to pay their bills. When the government reopened, back pay was paid, and they paid back Navy Relief.
All the civilians who were furloughed? They called us every morning, wondering if they could come back to work yet. I know that the shutdown hurt quite a few of the civilian workers on base quite a bit financially, they missed out on almost a whole months pay.
