The fact that you took "teachers should have a right to health and safety in the workplace" as "WFH only or not" is either naive or disingenuous. This isn't a binary, and I'm surprised that someone would assume as such.
What about literally everyone else? You are only making a case for teachers, who else should we be paying to stay home?
Democrats do with teachers what republicans do with cops. This strange do no wrong hero worship. I don't get it. Looking at our stats globally (reading and math scores/police brutality rates) neither deserve praise.
