As part of an ongoing effort to crack down on bad employees, Amazon is planting fake packages in delivery trucks to root out package-stealing drivers. Business Insider reports that Amazon plants these "dummy" packages with fake labels at random. When drivers scan the label, an error message pops up, which suggests the package isn't in Amazon's system and therefore won't be missed. At that point, the driver faces a choice: call a manager, return the package, or keep it for themselves. Though they don't publish internal figures, package theft is supposedly a huge problem for Amazon. "We might pull something out of our pocket and put it in there" to give it some weight, a former Amazon logistics manager told Business Insider. This person, who asked to remain anonymous for fear of retribution, said instructions for the practice came from Amazon's corporate offices in Seattle. "It's meant to be a trap ... to check the integrity of the driver," he said.
