I am interested in hearing other people's experiences. I teach in London, and my experience is that anyone who wants to teach science and maths is snapped up, over 50 or not. There are no where near enough applicants for the vacancies available. There are thousands of qualified teachers not teaching, but that is because they don't want to. Other posters have found that no one will interview anyone over 50, and say there is a glut of unemployed teachers in London. Over 50s don't apply for jobs because they know there is no point because they won't be considered, or they will be expected o work for free. I am interested to hear which is the more common experience.
