Can I get some help on this one? Is shifting trailors considered skilled work for a part-timer? I am getting all kinds of answers. If it is not, I can not believe it. How in the heck can the guy driving a shifter be making the same as the guy unloading the truck? All I can find in the contract is the part about starting back in 2002 for preload and sorters. The part about making $1.00 more per hour. I can find nowhere about shifters even being a classafication. Are shifters part of the carwash? What the heck are they a part of?
