The retail giant told one of its critics, Democratic Rep. Mark Pocan, $4: "You don't really believe the peeing in bottles thing, do you? If that were true, nobody would work for us.

Pocan had earlier $4: "Paying workers $15/hr doesn't make you a 'progressive workplace' when you union-bust & make workers urinate in water bottles."
