Please can people share their thoughts on the following. I am new to Headship (Jan 19) and have inherited an existing staffing arrangement. My school currently employs a teacher through a supply agency 1 day per week which is planned to be for the whole academic year. As I’m on half term now I can’t ask my business manager why we are using this model. My thoughts are that we should either advertise this post, or put this person on a one day a week contract, which would save the school a considerable amount. Can anyone think of advantages for keeping this person on supply? My business manager is typically very astute around the school budget!
