Do you know where your jeans or your child's favorite toy came from, before they landed on that shelf in your neighborhood store? Would it make a difference in your shopping habits if you could tell, with just a quick check on your smartphone, that the dress you're about to buy was made with slave labor? Free2Work thinks so...Free2Work is a new smartphone application sponsored by the International Labor Rights Forum, and it allows consumers easy access to information about the quality of labor used to create the products on store shelves...Free2Work assigns grades to companies on an A to F scale, based on each company's policy and record regarding child labor or forced labor.
