When ordered to do something inimicable to the company, get the manager to put it in an email or other written memo, "so i am sure i get it right". Protects you when later the fool tries to throw You under the bus for her mistakes!

I went through that similar situation whilst working on the Railways, we had a District Manager ( Boss of our Section) who was deliberately sent out into the ' back blocks' where they thought he could do the least amount of damage.
He was, and I'm being quite factually honest here btw, a complete and utter Dickhead which suited his name, that being Richard Richardson, a.k.a 'Dick da Dick', everything was run as if an Infants school child had been in charge, no discipline, no order, no directions from the top, just rank stupidity and childishness week after week.
Thankfully they replaced him with a REAL Manager and everything began to operate as it should.

If they are that incompetent they won't last forever. Not sure what your industry is but managers don't last all that long in my experience. Sometimes the worst ones go down the hardest. Keep your nose clean. Do your job the best you can and enjoy the show.

It's been a long time,but do companies have what they call "Lead Positions"? Not a manager,but kind of in between the workers ,and higher decision makers. Kind of a person who's been there, and has done almost every position on the factory floor.

I had one, and nothing I did (including filing multiple complaints with HR) worked. I finally had to quit.

By the way, she was the one who asked me why I abandoned my god.

I once had a supervisor who was less qualified for his position than me. I wouldn't say he was incompetent. He was partially responsible for hiring me, so he couldn't have been all that bad. I just did my job to the best of my ability. Mine was a technical position and his a combination of management and technical. Eventually, he discovered that my knowledge of the field far surpassed his, but he would do things that really bothered me. He would not give me access to some information that was critical to my job, which I interpreted as a way to protect his turf. He would often stand over my shoulder while I was working, questioning everything I did. I eventually stopped working when he did this and just stare at him (passive-aggressive behavior on my part?) until he went away. To make a short story long, I ended up creating my own position in the company, most of which was outside of his domain, and eventually became his supervisor.

Dilbert principle - it's what runs America businesses.

I threatened to quit and asked to be moved to another part of the company. That plan backfired when the incompetent manager was given half of my group, all the people I recruited, hired, and trained, and suddenly I was one of his peer managers. He eventually screwed that up and went back to the department he came from. Should have been fired, the asswipe. Kelly, you need to move to another manager, or another company. In my experience, this won't improve for you any other way.

Is he/she a relative of the owner? Blood,or through marriage? A longtime employee,trusted,but failing miserably?
