Summertime heat and the lack of air conditioning in trucks have long been problems for United Parcel Service, Inc. (NYSE:UPS) drivers. According to the company, this is because the delivery team makes “frequent stops, which requires the engine to be turned off and the doors to be opened and closed, about 130 times a day on average."
A former UPS delivery driver said it is company policy to turn off the engine and remove the keys at every delivery. It is a security requirement to keep the trucks from being tampered with while the driver is delivering a package.
