From what I can find, it seems that just brings more unnecessary hardship on themselves for no benefit to anyone.

Getting fired costs them their earned benefits, their unemployment benefits, insurance for them and their families, being fired makes it harder to get another federal position, and fighting it has legal costs they’d need to absorb. With people getting barred from their places of work, it doesn’t seem to make sense to think they can’t just lock you out when you go home anyway. With everyone above them being part of team Trump, they’re just spiting themselves. They already spilled the beans on everyone.

They’ve put up more resistance than almost anyone else has so far. They’re lawyers, not revolutionaries. Their responsibility is technically to be anything but revolutionary.
