I guess the difference is that instead of being fired, you most likely get to leave on your own terms that you dictate largely. What I mean is you don’t get fired, you resign, and can refer to the incident as you have resigned. If you don’t want to resign, you can most likely stay in the fucked up work relationship.

I guess the main difference is not what you get, but that Google would have to argue in court that it is fine to fire the guy. And the court case comes before the firing, so if it lasts 10 years like all those cases you hear about, the guy keeps being employed.
