Though there were many aspects of teaching I did not like, the 'superiors' who hated teaching and got out, then became 'consultants'.

I loved the actual teaching side of things.

I keep in touch with many of my students even today.

In Australia teachers are leaving in droves. They drown in paperwork, testing, and evaluating. The profession needs a revamp.

As for summers off, teachers here meet for planning in their downtime, so whilst it's a more relaxed few weeks when they meet, it would be hard to consider it holiday time.

Maybe try to do something else for a while and if the call to teach is still there, you will hear it.
