Morons run the Children's Home

Ok, so everyone is telling me I'm working Becca's shift. Fine, I'm ok with that now. Well, I go into work today and the new supervisor tells me "oh, we've changed your schedule". Get this bull shit. .. they've got me doing 2-11 Thursdays, 7a-5pm Fri-Sun. What the hell is that? No one ever leaves on time, night is when all the shit happens, and they want me to come home, maybe get to bed by 12, and be back at 7? Uhm, no mam. That's freakin' ridiculous. The more I thought about it, the more pissed off I got.. there is no way I'd be rested for a 10 hour shift getting off that late the night before. That's not even a shift?! WTF? I hate these freakin' idiots that can't make up their minds about what's going on. There is a shift that has that 2-12 slot on Thursdays, keep it there. Just because I'm technically an RRC, doens't mean you can pull that. I left my supervisor a note saying I was concerned about this, and would appreciate an opportunit to speak with her further about it, when it wasn't just a breeze through, here's your schedule. I'm so sick of this, and frustrated that I just want to quit and leave them hanging even more. errrrrrrrrrrrrrrrrrgh
