Amazon works in an industry where they have excellent control of employee safety.
Once again, you avoid confronting the many problems pointed out with respect to your posting. Perhaps you're too densely layered in stupidium to be able to recognize your own failings but:
1) You made charges of slave labor yet have done nothing to back that up, you cite no assessment by any United Nations commission, Amnesty Internation or other reputable organization.
2) You continue to rattle on about Amazon and your idiotically selected quote that proved only that a company that provides services to Amazon was cited for an OSHA violation. Whoopie. You continue to be oblivious to the fact that a company that that provides services to Amazon is not the same thing as Amazon itself.
3) You are blind to the many failings of Dow Chemical, even though they have been cited for thousands of OSHA violations, for instance in the Dow Chemical/Rohm & Haas plant in Deer Park, TX. In this one plant following one deadly accident, a plant that Dow touted as their safest of all, OSHA inspectors found 7 OSHA violations, in a single visit.
You also conveniently overlooked the previously cited notation that the US PIRG cited Dow as one of the 12 companies endangering the most people. That danger doesn't come merely from being in an intrinsically dangerous business, it comes from cutting corners, failure to implement and adhere to safe procedures, and failure to take responsibility for and clean up their own messes.
