Other than the parents having to deal with the kids being home (rather than being brainwashed), it seems to me that they’re doing the kids a favor by letting them stay out of those institutions, at least for one day.
well, that is a pretty good point
Forcing parents to scramble to provide baby sitters or worst take leave to watch their kids is very bad PR for teachers. Even poor people will start to grumble. Narrative for working parents are, we paid taxes and teachers are suppose to teach and watch our kids while we are at work!! Longer the teachers strike, the worst it becomes for them because the public will turn on them. Look what happen in liberal Chicago when the public school teachers struck.
