I have a job in an entertainment related industry that I've been working at for 7 years. In that time I have gotten only small cost of living raises even though I've been taking on more responsibility and some coworkers who were there a shorter time make more. This job brings in a lot of income for a side hustle of mine as it helps me to acquire customers and I suspect my boss is using this as an excuse to not give me raises.
What should I do in this situation. I'm kind of stuck working here because of the extra income that it gives me but I'm pissed that I'm not getting a raise and I can't quit because of the side hustle extra money, and my boss doesn't want to give me a raise. It's not fair that just because I'm making money from a side hustle I'm not getting a raise comparable to coworkers.
