Tough question! At the moment I am relying on trust and consistency. If parents are seeing me on a regular basis and offer a degree of flexibility then they will trust me more. I have been quite fortunate so far as I have only had one ‘cancellation’ and they paid straightaway as they acknowledged it is their fault.
At the moment I work on the basis of if I don’t turn up I don’t get paid. Though this is a slight risk, I like to think it gives both parties a chance to be consistent and trusting. I have given two clients a ‘contract’ which states stipulations such as 4 weeks notice, etc but in actual fact, it has so far not been needed.
Ironically enough, the only bad experience was when I just started and I received a text from a student who wanted lessons. NB this was not a referral from MGR!!! I arrived for an initial meet and the following week I taught a lesson. Then he cancelled the second lesson and didn’t respond to my texts for my 3rd and 4th so I just sacked him off. I found him a little irresponsible as he ‘manipulated’ this whole I am a ‘university student’ excuse too far!
All my current clients are working parents so I think they understand the fact that we as teachers need to work as well!
