Been there. Done that. Learned from it. Lesson One: Some employers are predators. That's their business model. They will not share the carcass. Employees get the bones to gnaw if the employer fancies himself generous. Lesson Two: Nobody would give me cheese with my whine. That hurt. I could fantasize eventual promotion for keeping the job, but it never happened. So much for fantasy. As my crude old granny used to say, "Wish in one hand and s**t in the other and see which hand has the most in it." The solution was to look for a better job on my employer's time. Anyone paying minimum wage is doing so because a. he's almost broke, b. he considers you next to useless, c. he thinks you're a member of a group with severely limited employment options (elderly, very young, poorly educated, handicapped, poor ability to speak English, etc.) and therefore he can get away with shorting your share. So, LEAVE. And no, don't try to bite him on the butt on the way out. He's bigger than you.
