Should I go back?

[Muki]

There are many schools that will require higher ranks to do some teaching from time to time as a requirement for their rank. However, that many hours seems a bit extreme.

I agree.

In my school this means assisting at classes two times a week: both in one day, each class 1 hour long, usually children classes. But nobody gets forced into doing anything they don't want/don't have time to do...

As an assistant you're not paid for your work, but you are exused of paying your monthly fees for compensation. Head instructors do get paid.

aigaios: you should first decide what YOU want. Then sit down with the folks at your school and sort it out. If you want to work for them - they should prepare a contract so you'll be able to decide whether you're taking the job or not. After 8 months of free labour - I think it's time for some honest and straightforward talking...

Let us know how things turn up.
