can managers fire their direct reports at most companies? not sure how common this is, but at my (relatively small) company, my boss cannot simply decide to fire me. he would have to go to the director (my skip level) or possibly a VP to actually have hiring/firing authority. of course, he's been there a lot longer than me and could probably persuade them if I was underperforming or causing problems.
