Well, their smarter because they know that the company doesn't really care about them. They saw their parents get downsized and outsourced because "Some indian dude that can barely speak-a-de-englrish is cheaper than their parents are. Who cares if it turns their personal life upside down... it got a bunch of CEOs big time bonuses and service sucked.
In other words, they are giving as much loyalty that they are receiving from the company... which is none.
I wouldn't go that far, but it would slow ops down. Plus, how would you handle, on route, a 149lb package? Can't stuff three people in a truck. What happens if you have a route that always gets "heavy" (50-75) stuff on pups? Is that going to go to heavyweight or are they going to give you a jumper all the time?
Don't get me wrong, I think that it's a good policy, but it's very shortsighted when the max package weight we accept (non heavyweight) is 150lbs. How often do we get stuff that's >75lbs? Rare... but I do handle enough that's 50+ on a daily basis to make this very concerning on how they are going to handle this...
