Charlie is an ideal colleague. He's energetic, knows how to handle bullies and has serious people skills. His work mostly entails riding on a cart pushed by Kim Headen, who fills orders in the warehouse at Replacements Ltd.
"He loves coming to work," Headen says. "He beats me to the door when we pull up in the parking lot. He knows his way in and to go exactly where I sit."
Charlie is a Yorkshire terrier. He's among the 400 people and about 30 animals who come to work at Greensboro, N.C.-based Replacements, where other varieties of fauna regularly come to visit.
