Don't sign anything, you don't have to.
Was this an official warning letter sent to your home or just a silly piece of paper informing you of the misloads? If it's an official letter a union rep should get involved.
tooner is a good driver and knows her preloader's work. A driver like her would quickly point out to management that you didn't load the package. I preloaded for three drivers and they all stood up for me when an air was found in the truck or something was just out of whack.
Seems to me if managment is crawling on you about misloads you can request more training, especially if they are actually warning you.
Trouble with the system is that union reps can't really do anything about them sticking papers in your face and saying you messed up. At our center they don't get involved unless it gets to warning letter stage, at that point they can have you request more training. I never had a preload sup with the balls or ability to offer more training.
