That wouldn't surprise me; the 'poorly treated' (quotes because it is a relative term, andI think that the Chinese are in fact bright enough to work out if they're unhappy with their treatment generally - the electronics firms aren't prison labour camps) workers are generally employed according to Chinese employment legislation - I think that even their pay is controlled - to a degree - by the Government.

There are plenty of sanctioned ripoffs in China, though. Less and less as they find their currency getting stronger and they're more reliant on Western firms for expansion.
