Whenever I leave a position like that -- toxic environment, horrible boss, etc. -- I like to imagine the shit hitting the fan after I'm gone. They'll finally realize that maybe they should look at changing some things. Except it doesn't much matter to me anymore since I don't work there anymore. Even places when I feel that I've been totally wronged, I like to think that they realize afterwards what a treasure they've lost (cough), but again, I'm gone and not coming back at that point, so it's a brief little fantasy and then I move on and forget about it.
