At my office, I feel the vibes here and know who's the goody goody and the a** kisser to the Managers/Supervisors. I have one person in my team that I vent to and we vent wtih each other. I trust her. After work, I don't think about work and leave it at work. I found that it really helps to have someone that you trust to talk to. I have learned that you never mention anything to your superiors about any of your peers. They don't want to hear it.
So, right now, I just do my job and I love my company and some of the people I work with. I don't confront people or tell them how they should be doing things. I like to remain as neutral as possible.
Hang in there Lise. All jobs have office politics, no matter what size the office is and what industry. Always carry a smile and that should help you get through your day. And keep work and your personal life seperate. I do this and it works for me, and maybe for you too.
