I probably had a stronger reaction to the government shutdown due to living in DC at the time, but 800,000 federal workers suddenly not getting paid (and without having certainty when it would end) isn’t something I take lightly. I know that the workers were paid retroactively, but that doesn’t help when your rent is due and you haven’t gotten a paycheck in over two weeks.
