I didn’t say non-unionized private schools were good/better because of their non-unionization. I’m saying your logic that because those teachers can strike, it is the root cause for why they don’t strike is a post hoc ergo propter hoc fallacy and provide what I believe is the alternative mechanism for why they don’t experience strikes.

There are absolutely folks questioning the utility of the winter and spring breaks in mass, as well as the summer gap, and if our agricultural society based education calendar is still appropriate today.

If you are dealing with district wide learning time loss, you absolutely do have to aggregate it together. Is each student going to ‘suffer’ the exact same? Not at all, some will have it hit them more than others. But you can’t just hand waive it all away. Those examples you present are individual kids and situation as determined by the parents. If school district decided to close a school for a month because of utility issues and just sent the kids home you’re sure as shit there would be an inquiry. If a parent took their kids out of school for a month? Sure as shit CPS and the school are going to have questions.

Strikes aren’t the only tool possible to protect teachers. They are just your preferred tool.
