Peak Mode is when a driver discards methods and sanity in order to get more packages delivered. It's basically becoming a runner and gunner and forcing a helper (if they have one) into the scheme. So, instead of one person grabbing a package off of the dash or floor in the cab and taking off at a sprint, there are two people. Add exceeding the speed limit, and any other possible way of cutting corners, to the scheme and there yo have it.....Peak Mode.
Peak Mode for a driver that is a runner and gunner every day of the year involves a seamless transition. All they have to do is coach their poor helper in the art of working like a madman and they are off to the races.
And al of this, of course, is supported by corporate.........as long as Peak Mode doesn't result in an injury or destruction of UPS or customer property. Because once that happens they'll just throw the book of methods in their face.
