I am a freelance musician so I do about 8 hours teaching per week and also orchestral/concerts/background gigs etc....
I've just been reading throught the missed lessons post. The reason that I don't have a cancellation charge is because I like to feel that I can call pupils last min (and by that I mean night befofe not hour before) to change/cancel lessons if I get a booking through.
I try to do this as little as possible but if a well paid job comes in and I have 1 pupil that day, I have to.My pupils are all happy with this arrangement as I explain my work before they start lessons but it does mean that I don't feel I can ask for the payment if they need to change their lesson or are ill.
What do other part-time teachers do??
