It's not at all uncommon - employees may be paid wages in form of the stock that hasn't passed quality control, for example the "Choco-pies" they wouldn't be able to ship anyways which are then used for bartering. It's also not uncommon that employees live practically in "labour camps" for minor offenses near the sites themselves, their basic livelyhoods covered by the site in return for practically servitude. Food for thought.Unrelated, but there's a Chinese factory where they pay wages with Choco-Pies.
wut?
