His point is he's been in an office with no fancy ventilation, in PPE and around sick patients taking precautions and is ok. Kids and staff complying with masks and appropriate measures should be ok. I'm not defending or denying his point - I am a parent and still scared - but my point is- teachers can't be the sacred bench warmers. They are essential workers- to me at least. And other essential workers are - no pun intended - making it work (thank you Tim Gunn).
