I would second the "public schools" line of employment. No stress and as long as you show up sober and on time, or close to it, your fine.

I prefer public middle schools since I worked in high schools in the states. Also, I am free to experiment to see what works with middle school
school students and what does not. Just keep it simple stupid. Explain and show them how to do certain things for no more than 3-4 minutes and let them practice. Change exercise every 10 to 15 minutes and it becomes a fun class. After the first month when they are not motivated to speak- show a short movie to get their interest back.

I have one rule- they can choose to do English in Class or homework. On a good day I get 80% speaking, on a bad day about 30%. I just got tired of screaming and tearing up homework.
