A lot of ignorance on here, especially the part timer that has fans blowing on him for his 3.5 hrs of torture. I'm a native of South Florida, when the bad beat starts its hard enough to do my weekend yardwork for 2 hrs without overheating, and that's stopping , and sitting in front fan when I need to. We have a job that does not allow us to stop and cool down whenever we feel the need.The ventilation in the trucks is pathetic, we wear dark brown, we work during the hottest part of the day, and with Orion spend more time than ever in the pc oven. Conditioning , hearing a lot of that. Should every driver sit in a sauna and do physical activities, in intervals ,to acclimate there body for summer heat? It's a lie to say our work environment and culture are not at fault.
