I currently work for an enormous, multi-national electronics distributor. I guarantee we have a store in almost every town, and the company just opened up almost fifty new ones just like the one I work in. I've been there just over six months, and in that amount of time, I've been able to become one of the top sales people in my store. Last month alone I beat out two full-timers (i'm only part time, since I'm also a full-time student) one of whom had been in the company and in sales for YEARS longer than me. I beat her, I beat the other full timer and I finished at a very very narrow second to my manager.
We are restructuring our store and two positions came open that would've been a huge promotion for me. Basically I would've gone from being the youngest and least experieced (but most productive) sales member, to being an assitant manager.
I found out yesterday I was passed over for another member who is a preacher with two children and can only work three days a week. He and some dipsh!t from another store that MY GOOD SALES HELPED TO RUN OUT OF BUSINESS.
Also, the full timer I beat in sales, who is a horrible leader, gets to keep her job.
