Fuckboy for a manager

Markell
So I know everyone has had that one horrible manager that was just despicable.. Right? Okay! So for the past 7 weeks my manager has been giving me 3-7 hours a week. (I work in fast food) When I first got hired I had reasonable 18-20 hours a week but then it dropped when he hired another person. However I work in a most white community (Birmingham, MI) but everyone I work with is amazing except for my manager. I seriously think he's racist because he only does this to me!!!! He gives the new dude 30+ a week and only gives me 4 or some BS. My boyfriend is fed up because I can't support myself off of $60 because my manager wants a senseless cunt who doesn't care. And this is my only job right now. I want to report him but I don't feel as though I have enough evidence to support my case 😣 and my boyfriend is so pissed that he's claiming to take matters into his own hands and I don't want anything illegal on my name!  Please help me
