Trump didn't mention the shutdown. But he should have. He should have said the shutdown is over and every federal employee received 100% of their back pay for the time they stayed home, drank beer and watched TV. So, obviously, they should have no complaints about the government-funded vacation (and silently hope for another one come February 15th).
Unlike in the private sector when employees are laid off -- they get zero back pay. If they return at all.
