I think there is a reasonable expectation that you don't sit in the truck with the engine running when there are reasonable alternatives. Most routes have reasonable alternatives. I don't think they expect you to freeze to death to save a pint of fuel. What they do expect, is that you don't use the the pint of fuel if it's not necessary.
What percentage of routes have no public place with heat on the route?
There you go using that "reasonable" word again.
"Resonable" does
not appear in the UPS corporate dictionary.
Here's how the process works. Telematics reports on our idle time, and some idiot with too much authority and too few brains sittiong in a cubicle someplace reads that report and sends an e-mail to the manager that his center's "idle time" is excessive. Said idiot then pulls a random metric out of his fat ass and mandates that the center in question will
not exceed that amount of idle time for
any reason.
The center manager has no choice in the matter. He will either generate the metric that the idiot in the cubicle is demanding, or he will be fired and replaced by someone else who can.
The idiot in the cubicle has heat and air conditioning and a bathroom 30 feet down the hall. This idiot has probably never even
been to the center in question, but he knows all about what goes on there because he reads a bunch of Telematics reports and has lots of maps, and 24 years ago he even drove a package car for a few weeks before he got promoted into management. This of course makes him
fully qualified to micromanage the center from a distance, and to make important decisions about idle time that will save the company lots of money.
Minor details such as drivers who need to use bathrooms or have heat during the winter mean nothing to this idiot. The only thing that matters is the metric.
