Finally sent an email to my buddy/head teacher about my ‘problem coworker.’ After our last class when they just screamed the whole time, never listened to me, she never said a word to them to make them be quiet, and she just left in the middle without telling me, leaving me really confused and angry.
I think I was fairly mature. I said that I would like to have more classes with the other teachers, instead of saying I never want to talk to her again in my life. I attempted to emphasize how much I liked them and did not mention that I kind of want to see her get hit by a bus like Regina George. I did not mention all the stress and crying and suicidal thoughts working with her has caused me. I did not mention how she is always late, sometimes never comes, sometimes sleeps, doesn’t do anything in the classroom other than purse her lips and stare into space with her arms crossed, lets the kids act like animals (crawling all over the desks, etc.), just listens to me scolding them without reinforcing, and all that. Or how she smells like poop. Because she totally does. But that is not relevant.
This is what I sent, via Cool Messenger:
Hello,
I have a question about the next semester schedule. I am wondering if it is possible for me to teach all of the third grade classes with you, and all of the second grade classes with XXX teacher. In third grade, I think that our classes work really well together and the students are always very respectful for you (same with XXX teacher.) I think that the students learn a lot in our classes and we also have fun. But the other 3rd or 2nd grade students don’t learn much (or anything!) in the classes because they are so noisy. They never listen to me and are always talking, and most of them don’t do any work. In each class, maybe 5 students listen and answer questions. After teaching many of my classes I have a really sore throat and feel very sad because no one cared about my lesson. Is it possible for us to teach all the third grade classes together next semester? I hope that the schedule can be arranged that way because I would feel a lot happier teaching the students here if they listened to me.
Let me know if this is possible! Because I really want to teach the students lots of English and help them!
