I've found another teaching position and have verbally handed in my notice. I've now received my new contract but my new school would like me to start immediately after June half term as their new timetable starts then. They will wait until September but obviously it would be preferable if I start with my new classes in the last half term of the Summer Term. HR have indicated that my headteacher is unlikely to find this acceptable while other teachng staff have suggested that I only need to give half a term's notice anyway. Does anyone know for sure what the standard notice period is in a secondary state school?
