I recently came across a list sent to me by an agency entitled Code of Conduct for Supply Staff. It includes rules on ID, appearance, punctuality, personal conduct, discipline and so on. For example:Appearance - Dress in an appropriate manner for school. Remember that appearances are important and that you should dress and act in a professional manner on all assignments. Jeans and trainers are not acceptable.Personal conduct - Be cheerful and polite. A positive approach will be recognised and remembered by your colleagues.Agencies seem quite keen to lecture supply treachers on how to be professional, without considering that it should apply to them. I wondered what you would include in a code of conduct for agencies. For example: Be polite, it costs nothing and remember supply teachers are paying your wages.
