Postbox letter from Darryl
Just saw an ad for a qualified math teacher at an international school for 75K a month. That's just over 400 quid a week and it's in Bangkok.
English teachers in Thailand actually don't do that badly
I am not trying to claim this is any type of scientific research with a high level of reliability or validity, just a quick check to get a basic idea about whether or not ESL teachers in Thailand are underpaid and exploited.
