Been at my company for 5 years on the afternoon shift. Originally there was only 1 shift and we split into 2 shifts and I took the afternoon shift which was supposed to be until the afternoons was strong enough for me to move to days. To this date countless people have come and gone from the dayshift and still I have not been able to move to that shift. I talked to HR, then the managers pulled me into the office because I talked to HR. They said they would get the ball moving to get me on days. Since the conversation they have brought on 3 other people for dayshift. The manager has asked for me to wait longer and now I'm fed up with it and ready to leave. I'm not sure if there is anything that protects me for a betterment of shift due to seniority or if I should just find other work.
