I have been working at an ups in georgia for five years. i have never been promoted to a preferred job. i sign the bid sheets every year and see people with less senority get promoted while i am still loading trucks. i want to cover drive and see people who have not gone to cover driving school, can't drive a 5 speed, and with less senority than me. I was told by some people with more senority than me to go to human resources and irritate them until i get a job. how should i handle this ?
