I know him very well. I worked for a company called "Sino-Can Bilingual Kindergarten" for the 2002-2003 school year. It was my first year in China. At the time, the foreign department was handled by a Canadian expat, and the salary was paid by David. We never had a problem with salary in terms of late payments or whatnot, but this was a long time ago, and with a different setup. After Sino-Can quit doing there thing at that location, David started up this Aus.-China school, the one you are talking about. This was his own venture, from what I knew of, so without the help from an expat to keep an eye on things at the management level, maybe things did go downhill.
I met him at a market near the school there, and he took me back to show me around. At the time, I didn't think it was too bad, but then again, maybe things went downhill after that. Well, if any bad things happen, I hope they don't reflect a worker that I know worker there, possibly managed it to some extent as well. Her english name is Hillary.
Toffa, I think you know who I am talking about. Was she still there when you taught? This is just something I would like to know, not someone I am trying to track down.
Anyways, good luck with your situation.
