Jessica and I, 2nd class citizens

How do u deal when ur coworker and u been treated like 2nd class citizens?
Well I meant relatively. A girl and I are treated the worst of anyone. Don't get me wrong. Our supervisor is fair and reasonable to everyone. And our other coworkers don't hate us. However, our supervisor seem to. For instance, we can't usually stay in the back room during our break. We have to go to the break room, which is separate. However, that rule got enforced most heavily on me and that girl. I saw our supervisor being nice to almost everyone else, but jessica and I got no part of that. Nor do we get away with talking to other ppl while working. The rule is u generally can't, but they get more leeway than we do. Jessica got sent home early recently and I got called in to take her spot. Even though my performance is good and I got along with everyone, I got warned twice not to get sent home. Our coworkers are awesome. They stick around and stuff. But still, sometimes I feel it's us against the world.

I remember when she got accused to using her cell phone on the sales floor. She didn't. And it was later discovered she was innocent. Yet someone else was using his cell. Jessica got treated worse for that than that guy. As for me, I remember 2 girls being allowed in the back room during break. When I asked why I wasn't usually, my supervisor said I make her uncomfortable with my body language and facial expression. Jessica and I don't seem to exist. I used to have performance issues but not anymore. Even my supervisor said I'm doing fine now. Still, all jessica and I stick together bc it seems the only way to survive.
