Who has asked you? Are you getting paid for them? A lot of staff run clubs in my school, but we do NOT have to and we get a day off in lieu for every half term of once-a-week, 45-minute-long sessions. Unless it is part of your directed time, you cannot be told to run clubs. We have football, hockey, newspaper, Forest club (outdoorsy stuff), cartoon drawing, sewing, multiball, story club, makaton and Wii Fit. In summer, some of the sporty ones change- rounders, tennis etc.
