Most LTL don't have drivers work the dock that much. Dockworkers do that. At my barn the biggest gripe for years has been too much dock work. In the next few years we will go to 100% dockworkers on the dock at the big terminals. We already have ALOT at my barn and I have no doubt more are coming. That being said, I can2 image why management would not work a driver on the dock and sit a dockworker at home when things slow down. Dock help is much easier to find than experienced, qualified, professional drivers.
