I work at a retail store in CA. As I was talking to another employee about wages, it came to my attention that she is making $2 more than me per hour. She just started the job about two months ago, while I have been there for 3 years. We work the same amount of hours each week. The only main difference is that I’m a supervisor and she is not. It would make sense that I would be payed more than her right?? After we had this conversation, I immediately asked my boss for a raise. She said that she is unable to give me one unless I can work 2 extra days per week (essentially full time). What do I do??
