You don't need to say anything in your resignation except that you hereby resign from the staff of xxx school wef 31st August. OWTTE.

I agree about burning bridges - I agree about the way education, and the school's gone in the last 20 years but I might need a supply job back there sometime, so I'm keeping my opinions to myself as far as they're concerned. IF you want my advice, do the same. Or not. Up to you really!
