Chicago, IL – Dozens of U.S. workers die every year due to heat, according to the federal Occupational Safety and Health Administration (OSHA). UPS trucks can feel as hot as ovens and UPS warehouses are almost unbearable in the summer. One memory burned into the minds of Chicago-area UPS workers is that of Stephen Michael, who died in a UPS warehouse in 2011 after his request to go home was denied, when he reported not feeling well during a day with a 109-degree heat index.
