Organized chaos: Are you adding to the busiest shipping day before the holidays?

MILWAUKEE (WITI) -- Monday, December 15th is the busiest shipping day before Christmas. It's so busy in fact, FedEx will ship 22.6 million packages globally. UPS reports it will move roughly 640 million parcels worldwide and DHL Express says its volume is up 40 percent.

When FOX6 News visited on Monday, it was organized chaos for Santa's helpers at DHL Express. Each parcel must be scanned and checked before it goes on its long trek. The shipments come from all over the place. Inside the trucks, there's hardly any space left.
