As long as the company continues to put more emphasis on the numbers and how it looks on paper, as opposed to doing what it takes to get the job done right, there are going to be misloads and service failures.
Drivers are not the only ones who are pushed to make "the numbers". As long as you've got someone breathing down your neck, pushing you to keep the preload off overtime and getting the sort wrapped up by a certain time (regardless of volume, etc.), there is going to be mistakes. And those mistakes go up exponentially when the time constraints are greater.
You can have your meetings and reviews and training and writeups and whatever, but that doesn't solve the problem. The problem is that a human being can only do so much work in a certain period of time. I don't care what the computer says (If the computer can do it faster and more accurately, then let it load the pkgs.). These numbers are based on the "perfect load". You know....the ones like you see in the videos. The ones where you could hold a dance in the back of the pkg car.
As long as you have human beings loading pkg cars and unrealistic time constraints put on them to get the job done, you will have misloads. And I didn't have to sit in an office for two weeks and "crunch the numbers" to figure that out. There's a lot of people who's only view of the company is the view they get on their monitor. I'm beginning to think that they would have to have a 100 page manual to figure out how to start a package car and drive it out of the building.
Of course, as always, this is just my opinion.
