To open, I am not an R&L employee. That said my company, A Duie Pyle has positions called swaps. Not at all terminals. Drivers start anywhere from 0900 to 1600. They do just that. Maybe a volume, or a small 2-3 stopper then do the swaps. The later guys will take empties, do swaps. When swaps are done , they may do a short linehaul. Seems to work out
