My boss and I don't get along. I've decided for my own welfare, it's time to move on. He only employs me grudgingly because of the time and cost of finding a replacement. He will not give a good reference, both because he doesn't like me, and he'll take it as a personal insult that I'm looking for employment elsewhere. If he gets wind that I'm considering searching for a new job, I will be booted out the door.
Of course, I'd like to display that I have been working and doing at least a decent job at my work, and need a reference. I feel my best bet for a good reference is to ask my direct supervisor, who has an excellent relationship with the boss. My supervisor is aware of the issues between the boss and I, and sympathizes with me somewhat. I can't speak on what sort of reference he would actually give me, but it's bound to be leagues and leagues above what the big boss would.
Knowing if my boss caught wind of my desire to move on, I'd get a boot to the backside, is it wise to ask my supervisor for a reference while at the same time asking him to keep it from the boss? Would it be wiser to instead simply not list either of them and rely on my interview to sell myself?
