Outdoor workers in Chicago face significant risks from extreme heat, which has become more frequent and severe. Cook County recently reported its highest number of heat-related deaths this decade, more than doubling the previous decade's figures. Heat is the deadliest natural disaster, surpassing hurricanes, tornadoes, and floods in fatalities. Without proper protections, workers are at risk of heat stress, which contributes to an estimated 2,000 deaths and 170,000 injuries annually in the U.S. The lack of federal and state-level protections further exacerbates the vulnerability of these workers, making local action critical.
