Congratulations on taking a principled stand. Few of us do. In case you need another reason to avoid masks at school, where mental performance is important:

Multiple studies find significant declines in cognitive performance at 1,000 to 1,500 ppm CO₂, a small fraction of the approximately 10,000 ppm associated with breathing through a face mask.

Phenomenal. THANK YOU for being one of the few teachers fighting for truth and actually caring about our children. I wish teachers like you weren't so rare. (I'm also sadly impressed by the fact that you write very well and intelligently, because I keep coming across teachers who don't, which also makes me worry about our kids' futures...) I hope you'll keep us posted about if and how they respond. They obviously cannot argue with anything you said.
