UPS drivers demand safety protections amid ferocious heat waves

When UPS truck driver Dwight started working for the shipping giant in 1998, he complained to his manager about the heat on the job, which was unbearable during long summer shifts. Dwight recalls his manager replying with an expletive: "Look at this f---ing rookie, complaining about the heat!"

In the nearly quarter of a century since then, conditions haven't improved for Dwight, who said making deliveries on his New York City route in blazing summer temperatures has sometimes brought him close to heat exhaustion. (Like several drivers interviewed for this story, Dwight declined to give his last name for fear of retaliation by the company.) 

"There's times where because of the heat, I felt dizzy, had to pull over and get out of my truck," he told CBS MoneyWatch.
