It is the 13th day of strike action since November by teachers at Forest Hill School for Boys in Lewisham, and most of the 1,400 pupils are at home again. Their teachers are protesting against staff cuts designed to save the school £1.3m. Fifteen teaching jobs are being cut from September, more than 20 support staff have already gone, and the head teacher is now grappling with a rash of resignations from disillusioned teachers who want out.
