When I was an hourly I worked preload one morning. They had me in unload and I grab a box and take a look. It was a FedEx ground package. It somehow got through CACH and was loaded into the correct trailer.
I like the story of the new driver who was messaged to go pick up a letter box & physically brought the whole letter box back to the center. Lmfao. Did that really happen, or is it just an old "brown cafe" tale?
