Because I honestly don't know how I am going to get my 11yr old to school if that's the case. He absolutely cannot stand being too hot - I'm already stressing about the compulsory tank top and blazer - he just won't cope in a mask all day. No official medical reason, he had severe eczema when younger and still has very sensitive skin but no longer seen by the doctor as we manage it with emollients and antihistamines. This is a potential nightmare for so many children.
By the way I am 100% for supporting teachers and keeping them as safe as possible, I think teachers are being treated appallingly. But I am coming at this from the child's perspective.
