I don't need to get rid of all of them. You might want to, but I just want the dead weight cut. The trick is to fire the worst ones last, because the ones who might have won a lawsuit will have moved on by that point.

If they sue, show up to court with boxes of written warnings.

The real trick is to make the positions of the ones who are merely entitled and incompetent redundant, because they weren't getting any work done anyways. You don't have to justify downsizing the same way you do firings in a lawsuit.
