hello. I am currently a head of department. I have accepted a normal teaching role next year rather than a managerial role that had been offered. I am now being asked to do additional duties for my pay protection. These duties are to be performed without remission. These duties involve curriculum based activities where am I asked to take a “lead” in one particular area - e-learning. There are also whole school duties such as supporting and delivering cpd events and training of staff.I am concerned about not having enough time to perform my full time teaching role. So my question is how much can a principal ask me to do during my pay protection period, without offering remission and how much can I refuse to do without being unreasonable.
