UPS doesn't air condition its trucks. This petition aims to change that - CNN Nurse Theresa Klenk sees plenty of cases of heatstroke at the New Jersey hospital where she works. But when her husband, a UPS driver, was admitted with symptoms incurred during a shift driving a brown delivery truck with no air conditioning, she decided to do something. Klenk created a petition on change.org in July urging UPS to provide air conditioning in its trucks. It's been signed more than 210,000 times. But UPS is not planning to equip its vehicles.
