I don't see why they wouldn't still pay you as a teacher. My sister works in a State Nursery school (not attached to an Infants/Junior school) and is paid on the Teachers' payscale. She previously worked as a Nursery Teacher in a Nursery attached to a school and was also paid on Teachers' mainscale. Presumably you don't have a Nursery Nurse qualification and so can hardly be employed as a Nursery Nurse. Their job is more a caring role than a teaching one anyway.
