I received training to become a super user on a perfect pick machine in the wearhouse I work at. The extra work I have to do comes with extra risk to injury. I recently learned the training costs $500 & I am the only one in my shift with this “special” title, but it came with no raise. When I complained about it a year ago they gave me a 50 cent pay increase, but I feel like it should have been more especially with all the extra responsibility I am forced to take on. My company is on a pay freeze so they aren't giving anyone raises. I'm not sure what to do. I don't want to quit, but I'm not sure how long I can handle the bitterness I feel.
