You don't get a job where your role is to make people's life hell, even for a few hours, if you don't have any inclination for it, these are unionized federal workers whose skills are transferable, not slaves. They are not bothered enough by their own and their co-workers behavior to resign, they self-selected.
Moreover, this entire "the bad people are coming to kill us from outside" is crap, Americans suicide themselves with their food, their cars (about 100 every day) and their guns. This is just pandering to the red necks.
