The worsening conditions affect outdoor and indoor workers alike, with risks ranging from heat-related illnesses to respiratory issues caused by wildfire smoke. Vulnerable groups, such as temporary workers and those in physically demanding jobs, are particularly at risk. Without adequate protections, these hazards could lead to increased workplace injuries, long-term health problems, and reduced productivity. The lack of comprehensive federal standards to address heat and air quality issues further exacerbates the problem, leaving workers dependent on employer discretion.
