I think the fear was that teachers would get the virus and then have to duck out. Even worse, many of the sub teachers we had in school were semi-retired teachers who would be even more vulnerable. You could make a case for putting up a plexiglass wall between students and teachers just to end this headache and I think you wouldn’t find as much opposition now as you would have in 2020. That said, some kids have to be physically restrained/handled and you can’t very well do that behind plexiglass.
