Organization: U.S. Postal Service, Washington, D.C. Agency: Campbell-Ewald, Warren, Mich. Market: Shipping managers, office managers Quick chase: A woman walking through her office with a package is confronted by co-workers who want her to take their packages to the post office. Even as she tries to sneak past some of the cubicles, her load of packages continues to grow. Her desk is buried in packages. But behind the clutter, the woman is working the USPS web site, which allows users to pay postage, get insurance and print labels. When a postal worker shows up to haul it all away-for free-she admonishes him not to tell her co-workers, who think she's at the post office. She's actually enjoying a sandwich. The brightly produced vignette underscores a problem and offers a solution. Clue: She goes postal but in a good way.
