I work in DC. Fortunately not for the federal government so I won't be affected. I feel bad for all the people who work in restaurants, etc in DC. Their business will go way down and they won't be able to recoup those losses.
Yes, I was a government program manager in DC during a previous shutdown before we had kids. When we came back, a lot of the faces at the local eateries were different, and several pick-up places went out of business shortly after that. The coffee lady I always got my morning brew from had to borrow money from relatives to stay in business. She was studying engineering in the evenings at the University of Maryland. I often wonder if she finished her degree.
Some of my contractors weren't paid during the shutdown, and others were moved over to other contracts with state and local governments and no longer on my contract when I returned. Several of the IT support people assigned to my office found other work during the shutdown, and the contractor didn't have enough people to help everyone with computer problems when we returned.
I had a huge backlog of Congressional inquiries and all kinds of contract issues to deal with when I returned.
Thankfully DH and I were both working then, and we just used the time off to paint a few rooms and thoroughly clean the house.
