Working double in a single room...

I have come to believe that I cannot believe anything my boss has told me about my job because everything she said would happen has not. Today, for example, I had 21 students, I am only suppose to have 12 at a time. Today I learned in my meeting I may have up to 24 that I have to "service." They failed to tell me yeah, I can only have 12 in my room but I can have another 12 working on the pod (which is what they call where they live and eat). Not only did I get guff for that but also I got some guff for not helping out another teacher who takes an extra class period because of the extra students that I have in my side of the building so they can have PE. Argh! Needless to say I will be staying after to prepare myself and help the other teacher.

I just am getting frustrated with a lot of stuff at work. I like it but it seems as if they drop stuff on you that they have previously said wouldn't happen and then expect you to have expected it. Oh well, my wining won't help me out, as long as I still get my paycheck that is all that should matter.
