The problem with Peter Harvey was who in hell’s name let the bloke return to work when he was clearly still unfit.
Even in my day, certain teachers were hounded. And at least 75% of those you would NOT have dared do it with never used CP nor would they have called the Head to sort it out.
I suspect Doc himself would have garnered that respect at any time & in any school system with or without CP. And part of that respect is from your fellow teachers. Which also makes me wonder whether Mr Harvey’s colleagues were disdainful of him & this spread to the kids.
