14 Years of Loyal Service in a Fabric-Covered Box Anyone who works in a fabric-covered box can relate to Dilbert. Since 1989, Dilbert has been the touchstone of office humor for people all over the world. As long as there are corrupt businesses, inept bosses and downright loathsome co-workers, there is plenty to chuckle at. Convinced your co-worker is a demon? That your boss is incompetent? That your dog is out to get you? Dilbert believes you, and this book proves it.
