Hi there, my school carries out a fortnightly 20 min training session which takes place before tutor time on my day off. Each Dept takes a turn to deliver a session over the year. A member of my Dept has already delivered one this year. My line manager came to ask me this morning to deliver one. When reminded these take place on my day off, he asked me to choose a different morning to do it (this week). Should I do this or should I avoid it as it is something which happens on my day off? By the way, this is not part of our whole staff CPD programme, it is an 'extra'.
