Respect is something you earn, it's not a God given right that goes with a position. I work for somebody (1 line removed thank heavens) who can only communicate with me through screaming increasingly. Luckily she makes herself look stupid and I'm not adverse to the odd caustic comment in retaliation which draws her in even more. Although she's got a temper on her, she's not naturally given to conflict, and thus tends to come off second best. So long as you're not that desperate about your job, it removes the ultimate sanction from them, and once a bully can't play that card, it gets difficult to threaten staff. I'm slightly lucky in so far as I can occasionally invoke a procedure for refusing an instruction, and have done so, which really annoys her as she's never encountered someone who just refuses to obey before, as I understand it.
You do get the odd pyscho of course who gets off on being hated and actually confuses it with being a good manager. Such types usually have a wider pathological neurosis and it isn't difficult to spot the source cause. I've only ever worked for one, and senior management should have intervened much earlier and removed her. Instead they waited for her contract to run down, and didn't renew it. During this time though it caused a lot of distress and everyone got damaged to a greater or lesser degree. A Pyrrhic victory ultimately, but not one of my happier times.
You do get another type as well who suffers a personality transplant the moment they get a small promotion and go from being amenable to autocratic and aggressive with it. I've encountered that a couple of times, and resolved it once when there weren't any witnesses around 
He never did it again, but continued to pick on others.
My own experience of management was that I preferred to be liked, but didn't crave popularity to the point where it became all consuming. Provided I could coralle the anti's into a manageable and predictable little coven, I could handle it, so long as I was able to carry the majority and more important elements with me.
