Yes, I know.
Some years ago, I saw a flow diagram that clearly demonstrated just how difficult it is to fire a GS employee.
Boggled my mind - it takes years, costs a lot of money and time, and, generally is not worth the considerable effort it takes to get done.
So, the disfavored employee is shuffled off to a “safe space” and allowed to draw pay and benefits. Paid for doing nothing, but no longer able to throw sand in the gears!
And do you remember how, not too long ago, the President wanted to change the civil service rules so they could be fired. Folks went nuts, he was sued( I believe...imagine that), and the change went nowhere. Nice racket, if you can land it.
