As others have said, it's only a matter of time. We've all seen those guys checking their time studies on the chart and sweating over their numbers every single morning and going through their entire truck and helping their preloader off the clock. We know some of them are out there breaking every rule and cutting every corner just to get an attaboy from management. They are setting themselves up for disaster.
These are the same guys who are sprinting off every stop, jumping in and out of the truck, leaving piss bottles in the back, speeding, rolling through stop signs, running red lights, cutting people off, sitting on their seatbelts, sheeting air and pickups off area, futuring missed pieces, not reporting misloads, bagging packages, signing for packages, lunch running, and not reporting minor accidents.
Just wait. Eventually, they will have a tier 3/serious injury/termination for dishonesty. That is, if a warning letter doesn't wise them up first.
I will say though, it is very frustrating as a cover driver to have to run a route that's been destroyed by runners.
