Im a part time package handler, been working for 11 months. Never called out, always on time, never complain. There is a 1$ skilled worker raise that you get if you know the sorts. I've known the sorts for a very long time now, and i asked for the raise. My sup told me that i need to prove myself...then i ask my other coworkers when they got theirs if they had trouble like i am. They said no, and they got the raise immediately without needing to prove themself or to go up and sort. Im a loader and i caught 6 bad bags in one week (which is a very big deal) My sups then say good job, you broke a record blah blah blah..like i don't care just give me my raise. 3 weeks after i ask i ask again and they say they are working on it. What should i do??
