An acquaintance of mine I met while working a help desk job: He was in process of getting his degrees to become a teacher, did so and taught high school math for 5 years. As much as he loved, and took pride in, the work he did with teens and making a difference, the continued stress of a bullshit administration (at 2 different schools and districts) took its toll. He left, becoming a corporate training (see, still teaching) and I’ve seen a marked difference in his attitude and life. He has less stress and a fatter paycheck.
Teachers shouldn’t be put though the wringer and not be expected to react. “There’s no workers shortage, just a shortage of slave labor” is more evident in their profession than any other (outside possibly food service).
