Yup. Teachers in such situations don’t really teach. Instead they manage (to varying degrees of success) classrooms.
My sister is an elementary school teacher. She loves it. Very talented, dedicate, always highly rated to the point where parents of students request their kids be placed in her class.
However, she teaches in a private school, having given up on the public schools after a few years of utter hell being caught between disrespectful kids, a callous school administration, and parents who were either completely disengaged or confrontational in blaming her for their kids bad behavior.
And this at the ELEMENTARY (2nd and 3rd grade) level. It got so bad (kids threatening her) before her switch to the private school that my wife and I were working on lining her up with a good corporate education gig (which is sort of like teaching 3rd graders) and telling her to be ready to submit a no-notice resignation when she got an offer.
My wife is spec ed teacher in a public school. She likes that the administration pretty much ignores the spec eds so she gets to teach real subjects which some of her kids do well with. She has had a couple that should never have been referred for spec ed but their parents do not want that situation rectified because their kids are learning to read and write and cipher which, in the other primary classes is best done at home. Both of us think that people who care about their kids should sure as hell be teaching them outside the public schools.
