INCOMPETENT MANAGER

I'm a bit sick of working in this company. Too many workloads but no rewards, also a double-faced manager and a stupid system are enough to tire me out. I didn't know a good mangement was so important. My manager isn't a good leader and she likes to shirk all responsibilities and pretend she doesn't know anything. If she likes someone, she will appreciate no matter he/she works well or not. If she doesn't like someone, she will only see his/her bad side and weakness. Too subjective!! Is it what we should learn to survive in a company? Too butter up your boss? I really hate that!!
