You Had One Job! collects the best of the worst workplace bloopers for fans of fails everywhere. The biggest blunders bring the biggest laughs. That's the idea behind the best-selling You Had One Job! calendar, which features the funniest photos of on-the-job mishaps and miscalculations. Each daily page features an obvious oversight, half-baked flub, or silly slipup paired with the snarkiest of observations from humor writer Beverly L. Jenkins.
