At least freight isn't as bad as parcel yet.
Parcel drivers have supervisor go on ride alongs.
The supervisor writes down every area of the parcel drivers route that can be improved on.
They also count the drivers steps,and one parcel driver told me they measure their stride,if the supervisor thinks the driver is walking to slow,he walks to the door of the custoimer and writes down what he did.
Alright then as far as using the waiting for door item on the Diad.
That won't always work,maybe once in a while but if you make a habit of it you will get busted.
Just think Zabasearch,and Google Earth sites will take anybody on their computer from a satelite,way up in the sky,all the way down to anybodys front door.
If anybody can do that on their desk top,or note book for free.
Don't you think UPS can also do that looking at the route drivers?
Heres my solution for unwinding at the end of your hard day without being terminated.
Just clock out,and you can have all the time you want to rest up.
Or you can always resign,buy your own truck,then take as long as you want between stops,as well as all the breaks you want.
When one of my co-workers would whine to me about this topic I'd always say you gotta do what they want you to do when the one that has their name on the equipment,also is on the paycheck.
