How do I deal with this situation?

[Monkee4]

My boss of 2 months is majorly passive aggressive. Behaves like a child, ignoring or cold shouldering me most of the day. Micro manages me, criticises when I am talking to clients etc. Slags everyone else off if they make a mistake. They are all idiots! Thinks other people are really rude (when it is actually her who is rude) We share an office and are together most of the time so I have no escape. The others in the company are really nice but work in other departments. I really like the company and it is so convenient for me but I am not going to stay and be made to feel like crap. If I say anything like "what's the matter" I know she will say "nothing" like a sulky partner. Any advice, wise mumsnetters ?

Is there anyone above her you can go to?

Otherwise, look for another job or just ignore and know that it's nothing personal.

I could talk to the MD and have been thinking of it but he is really old school and I know that would make things uncomfortable for him and ultimately me. The passive aggressive boss has been there nearly 30 years so is pretty much part of the furniture. I am sure I won't be the first to leave because of her however but I will be really sad if it comes to it.
