GAC Nightmere Poster,I agree entirely with what you say. Furthermore,any foreign teachers teaching GAC in China run the risk of being cheated re their final month's paycheck or air fare reimbursements or bonuses due,in the event of a GAC Center being in financial difficulties.
It's also worth adding that some parents might well give you grief by complaining that what you're teaching is either too difficult or too easy for their spoiled offspring.That would not be a good situation to be in at your workplace,would it?
I came upon this thread on another forum re GAC in China. What has been posted there backs up what we can read about the GAC scam in China on this board:
