So Amazon installed vending machines to dispense free OTC pain meds for workers, who swipe their badges to get the meds. Guendelsberger points out that while an initial reaction might be "oh, that's nice of Amazon to give away the pain meds for free," an *actual* nice way of dealing with the problem might be to give workers shorter shifts or more breaks.
