Where else are teachers not paid for prep time? Last spring I did some teaching at a university. It was my first time. It was a temporary position. I was there 1 semester only. I was paid by the hour.

A couple of things caught my eye about the arrangement:


They only paid for the time I spent teaching in a scheduled group setting.
They did not pay for prep time.


By prep time, I mean the time I spent getting ready for a particular class. I saw this term being used elsewhere on SE Academia, not sure how common it is...

In what countries / universities / contexts is it common to not pay teachers for the time they spend preparing a lecture?

FWIW I was teaching an undergraduate media studies course at a private creative industries-type university in South America.
It is quite common in the UK for hourly payed lecturers to bill University for contact teaching hours only. The rate is usually significantly higher than the hour worth of a full-time lecturer, to account for (unbilled) preparation time.
