So, Charger (the carrier) calls a broker on a load and indicates that they want it and will call right back. Then Charger (the carrier), walks across the hall and gives that load to Charger (the freight broker) to cover. Pretty much a classic case of double brokering, leaving the original broker with the impression that Charger (the carrier) is hauling the freight.
Just built a decent sized yard in Woodstock and they're working on the office building now. Should be up and running shortly i'd guess.
