Pees in the brown Koolaid
If in the situation you mention, the two routes have the same load quality, same quality of dispatch, same quality of trace, same amount of missorts, etc., then there is something wrong with the time study.
From my experience, those things I mentioned (which are out of the drivers' control) are the biggest factor in overallowed.
A manger that manages only by overallowed, is the problem....
P-Man
The issue, however, is that none of the problems you mention will ever be fixed.
Regardless of how wrong the timestudy might be, it is chiseled in stone. We are bound to the numbers, no matter how divorced from reality they are.
And a "manager that manages only by overallowed" might very well be the problem, but he is also the one who is going to get promoted; unfortunately, that knowledge does nothing for the driver that is being harassed and spending 10 hrs a day busting his ass on a route that is coming out as an underload on paper.
The flawed time allowance is a cancer, which managagement is more than happy to cure by applying the Band-Aid of the drivers skipped lunch to it.
