I’ve been working at this job for a few months, just a few weeks after it opened. I’m making 15/hr which is good for this type of job, just need to work to get through college. 3 people in my department were either fired or quit recently so they hired someone 2 days ago who told me that she is making 17/hr. I’m shocked especially because there are talks about me being promoted. Also this girl is friends with my supervisor so that’s probably why. Everyone is telling me that I should use this as leverage to make more money but I think I’m going to quit because I am so angry and take everything personally. Any advice?
