I see the gray areas and I let my conscience and my sense of integrity guide my actions.
That is why, when I was driver, I started my lunch when I broke trace and started driving to where I was going to eat lunch and ended it when I picked my route back up where I left off (maybe not to the second but close within reason).
No one had to tell me this ... I just knew it from my sense of right and wrong.
I don't judge others on this ... I am responsible to and for myself.
When you were a driver the truck was not equipped with Telematics and you did not have some IE guy questioning why your truck might have gone 401 meters "off trace".
For the most part the method you described is fine and I agree with it. In most cases we should not be billing UPS for the non-productive time we spend driving the vehicle to a preferred lunch location
if other suitable locations are available that are closer or on trace.
If, however, I am working as intructed...following
your trace and meeting
your service requirements (NDA by 1030, savers by 1500, no business deliveries between 1200-1300) and said trace puts me into an area with no suitable lunch or break/restroom facilities....then you will either let me drive your truck to a suitable location on
your time or you will install and maintain some sort of toilet and handwash facilities in the vehicle or position them along the route.
Human beings need to poop, wash their hands, and eat...and no amount of IE micromanaging will ever change that fact.
