Worst possible manager ever?

The title makes me chuckle because I’ve not had managers for a long time, but in the past I have come across right arseholes. The term worst possible manager must be applied to one of those boys or girls that make your skin crawl, the type that you know deep down inside are plagued with self-doubt, are passive aggressive or whatever and yet put themselves in the cross-fire of you.

I jest somewhat here because all companies that reach a certain level obviously need management, no I’m not disputing that, of course we need managers, but we need GOOD ones, intelligent ones, good communicators right?

SO anyway I just wanted to put this out there to see if you wanted to share your worst possible manager experience with me, and why do they get the prize? – it’s just a bit of fun.
