First, lets look at the raw numbers on this. 508/14hrs ( the max you can work in a day) =36.28SPORH. Now with that number, we can extrapolate 60mins/36.28 =1.65 per minute. So within less than 1 minute on average, you were able to 1. stop the vehicle, dig out the package/s (at least 508 packages on the vehicle, at 1.5 per stop would be 762), scan and take the packages to the stop ( accounting for the fact you also have a helper) get back in the vehicle with your helper, secure your seat belts, start the vehicle, and move to the next stop, all in less than 1 minute per stop.
None of the above time accounts for lunch, to or from building time, picking up said helper, gassing up, or in building time.
And all the while being safe to yourself, your helper, and the general public.
I call BS and if not you're a injury to yourself or others looking for a place to happen. Not sure whats worse, bragging about you being unsafe or management looking at a report and not addressing there is no way to do these numbers without glaring safety concerns.
Edit: judging by your "y'all's" tag you might be from down here in the south. I'm out of Roswell Center, local 728. Get to know Matt H our BA, I have a feeling you'll need to call him with an issue eventually.
