The linking of Isle of Man teachers' salaries with pay awards in England has led to a "huge erosion" OF wages and must end, a union has said.
National Association of Schoolmasters Union of Women Teachers (NASUWT) has formally rejected the government's latest offer in an ongoing pay dispute.
Damien McNulty of the NASUWT said an "Isle of Man specific" pay arrangement was needed.
It comes as National Education Union (NEU) members accepted the deal.
