The lesson: worry about the relationship you have with your boss at least as much as you worry about your job performance. If your boss makes a mistake, see if someone else other than you will point it out. And if you do highlight some error or problem, do so in a way that does not in any way implicate the individual’s own self-concept or competence—for instance, by blaming the error on others or on the situation. The last thing you want to do is be known as someone who makes your boss insecure or have a difficult relationship with those in power.
