On June 25, 24-year-old UPS driver Esteban Chavez Jr. collapsed in the back of his truck while working, and died. Temperatures in the Los Angeles area that day were in the high 90s. Hundreds of other UPS workers around the country suffer from heatstroke every summer, as UPS refuses to install air conditioning in its trucks or warehouses. In our own Teamsters Local 804 in New York City, a supervisor even told a driver who was suffering heatstroke while working not to call an ambulance, and tried to keep him from filing a workers comp claim. Later that day the driver was hospitalized for heatstroke. And, though we have a contractual right to have at least fans in our trucks, in New York City UPS refused to install fans for months.
