I'm sorry but giving students this level of flexibility makes it impossible for me to guarantee a good service.
I need at least 24 ahead notice for any changes.
If that level of flexibility is important, than I suggest allowing it only to paying clients who have a good track record.
ONLY students with a record of paying and showing up to lessons should have that flexibility. New students should not, especially those who are doing their trial lesson.If it's important for Preply to enable their teachers to provide good services, then teachers need to be respected more. Especially their time. We are not on-call and ready to hop on a lesson. We are professionals who pride ourselves on delivering quality services. I organize my whole day arrive these lessons! I don't have time to work with clients who are not serious and those who reschedule lessons aren't serious, especially if it's their 1st one.
