Are all bosses this crazy? Or just mine?

My boss is insane. She demands schedule changes from an entire department, which is fine, but she'll send an email out a 6:45pm (after everyone has left) telling us that the changes to our schedule needs to be "effective tomorrow."

If you ask her more time, she refuses, and says we should always be prepared to have our schedules adjust at a moment's notice.

She assigns projects in a very general way, never gives any details, hates being pinned down for the sake of details, then chews out everyone in the building when the results do not contain the details she was hoping to get. If anyone ever asks for clarification of anything, they get criticized via global email for "not being on the same page" as her.

If any employee notices a problem that needs to be fixed, that employee will be blamed not only for the problem happening in the first place, but will also be forced to take on the role of making sure it never happens again, whether or not they know anything about the process that caused the problem in the first place.

A fellow employee's mother was in the hospital, and they thought she might not survive, to which this boss commented, "Oh, great! Another distraction."

She micromanages (which is not that big a deal, all bosses do this), but when she micromanages, she makes knee-jerk reactions that change the entire scope of the company because of something she overheard spoken by one entry-level employee one time while in the break room.

She works 80 - 90 hours per week, and expects all managers and supervisors to put in 60+ hours per week at the office, plus telecommute from home, and since we're all on salary, we get no pay for any of this above 40 hours.

I was "promoted" into a position I do not want, am not qualified for, and never expressed the slightest bit of interest in. I was not given a choice. I was told that I simply had to do it, effective "tomorrow." I was not given a raise. I voluntarily gave up my raise last year to help the company, and may have to do the same thing this year. My job description still has not been changed to reflect any of my new duties, which as far as I can tell consist of whatever the boss says to do from one day to the next, without any regular work at all, and with nothing written down.

When I say that she is my boss, I mean she is EVERYONE's boss. She's the CEO, so it's not like I can go to a higher authority.

I appreciate that our company would proabably not exist if she were not such a crabby lioness, but I often feel like we, the people who work for her and keep her company afloat, are treated like part of the problem instead of being treated like the only solution she's got. We all work VERY hard, so I don't like getting screamed at live on our call-center floor (or anywhere else for that matter) for something I don't even understand. After being chewed out by her, I am always more confused than I was before.

I would look for another job, and I have looked (and was interviewed by another company), but right now there's so many people out of work and willing to work for less than I'm making, it seems like my only alternative is to suck it up and take the abuse until the job market actually shows some spark of life. I would even take a cut in pay, but I do still have a family to support. Still I'm not finding anything else. I suppose I'm lucky to be working at all right now.

Since this is basically the only company I've ever worked for other than the U.S. military, I was wondering if other people out there might have similar horror stories.
