This past school year I did loads of stuff that is wholly not my job. Some of these tasks should be taken care of by our administrators and some should be completed by a collaboration of multiple teachers. We got a new admin team and had many (more than 50%) new teachers on staff last year, and I offered to help with some things, but then I somehow became the "person who organizes things" and I'm worried it is now the status quo. It was an entirely way too stressful year and I need to focus on keeping my own stuff taken care of, rather than arranging school field trips and school events. What's the best way to back off from these tasks going forward, especially in the eyes of admin? No one else at my school is stepping up to do these things that are yearly events, and I can't plan everything. I've recommended committees to admin but overall, I don't think admin cares about burnout or equal division of work, so it doesn't matter to my P that everything is being planned by only a few people. Obviously the "just say no" approach is the most direct but I don't want to be labeled as noncooperative.
