So today I was reminded that I am not an equal

Rumors have been swirling at work that the new guy (he's white) I am training was being paid more than many of us are being paid. I've been brushing those rumors off. He's a new grad. I was thinking no way.
Sure enough, I went HR, just for the hell of it. They wouldn't confirm, but they didn't deny it- But they said, " you need to talk to your manager about your own pay rate". - which pretty much confirmed the rumors for me. Anyhoo, HR guy contacts my manager - who then calls me with some BS excuse saying " oh looks like we made a mistake when we did our numbers in Jan and you got left off, I don't know how that happened, I'll make sure that gets fixed". So now they will give me a raise. - But it felt like a kick in the gut. How insulting to think it was OK for me to train someone who was getting paid more than I was? I am his superior - how can he make more than I do?

This has ticked off a bunch of other nurses on the unit that are now thinking about leaving after finding out how much this guy is making fresh out of school with no experience. I guess thats white privilege at its finest. Walk out of nursing school and make the same pay rate as nurses with several years of experience.
