Work Politics is Getting Dirty at McDonalds

I started at McDonalds in Oct 2003, That’s like 2 years and 5 months.
For the last 8-12 months I’ve been on 3 trials in order to be promoted to a crew trainer. It is something that I have wanted for a while and has seriously grown on me. I found it very hard as a very keen trial crew trainer because I am to prove that I could do it, act like one and take charge. I constantly had problems with crew saying that I could tell them what to do cuz I wasn’t a trainer or anything, so I wished i was a trainer and believed it would solve this problem and people wouldn’t complain because I did had authority.

About a month ago I found out we needed more shift assistants, crew chiefs and crew trainers. So my aim was to be promoted to a trainer asap. We also had gotten a new store manager 4-6 months ago. There was myself and another girl(best friend @ work) that were keen crew wanting a promotion at work and the new store manager was saying to us since starting there that she needs shift assistants and for us to put our heads down & work towards that.

Last Tuesday me and her were promoted from normal crew straight to crew chiefs! This is a double promotion and seldom happens. Now, I’m a chief I’ve been told (from a manager) that “a few people didn’t agree with the promotion mainly crew”. These people are rude and one particular one is a trainer and has been for about 1-1 1/2 yrs and wasn’t promoted. She is saying to managers that she can’t believe that I was promoted and told the other girl (my best friend @ work) she can’t believe I was promoted, and I didn’t deserve it. Now I’m a chief and try to act like one as I could be getting promoted to a shifty in about 3-5 months if I continue to grow. I find it hard though as crew are jealous and rude to me cause of my promotion..

Help me!
