25 classes. 500 students. 6 art fairs 0.8 not full time

My family moved to this town for the school systems. I am disenchanted teaching in it. I was really excited they were hiring an art teacher for the elementary school. Turns out it was for 2 schools and still only a .8 position. They use 2 art teachers per 3 schools and it's not full time for me.... we pay $1000 a month in property taxes, the majority going to the schools and they nickle and dime the art, music, and gym teachers into multiple schools not full time. I have 25 classes, 500 students I see each week at 2 schools. No breaks between classes aside from lunch and a planing period. There are 6 art fairs total a year, it's a ton of work. I'm so disenchanted by the school system. It's nice being on the same holiday schedule as my kids but why are they trying to coupon code speacils teachers? So many art teaching jobs are like this now. They brag about their art program. They have 6 different art fairs between the schools it's too much. It's never ending work but they only have a 0.8 art teacher position? How can you make part time salary and be expected to do so much extra? If they just had 5 min between classes it would add a whole extra day. They smash it all together into an exhausting marathon.....and it's somehow not full time. Sorry for the whine, I'm just really frustrated today.
