In regards to AALC in Thailand. Stay away from this agency. You will not get paid. They will steal your money. They do not follow the terms of their contracts yet hold you to your expectations. This agency is very corrupt. Watch out!
I would agree with Turnoi.
From what we can see, their website is painfully minimal. It says something about the school.
If a teacher has sufficient financial resources so he/she can teach without being paid, or being paid very little, as an adventure then it could be fun because Thailand is beautiful (and the president looks very handsome). But if the teacher is dependent on getting a regular paycheck from that school, then it can be quite stressful.
