As Texas baked in this summer's record temperatures, local UPS driver Chris Begley started feeling unwell before collapsing at a customer's premises. In a statement to local media, UPS said it was cooperating with the authorities as they investigated the cause of death. "We train our people to recognize the symptoms of heat stress, and we respond immediately to any request for help," it said. Many European and other usually temperate countries still have no laws establishing maximum work temperatures. "Climate change is such a paradigm shift that all of us need to rethink these legacy economic assumptions," said NELP's Christman.
