搞好人际关系和工作能力同等重要。If you want to stay...you need to do...

1. 深谈一次，撇清误会。
2. 和经理one on one weekly or biwekly, 名为谈工作实为联络感情交流想法
3. find a chance to buy her a coffee or set up a team lunch or bring some home made treates.
4. small talk - look for common topics - kids, shopping, something is on sale, dresses, etc.
5. give compliments, i.e. You look great, nice ear ring, I like your dress. Where do you get your shoes? It looks great on you.
6. 尽量少跨级complain. what goes around comes around. if you say something bad about your manager, she will know eventrually.
7. "我是心里不太看得起她。因为她自我感觉太好了。到处指手划脚", this is wrong, either way, she is your manager, if you keep thinking that way, you won't be able to get along with her.

化敌为友才是王道！

Good luck!
