Jerry Gergich
It's easy to determine that Jerry Gergich was easily the worst employee in Pawnee on Parks and Recreation. His reputation as a total screw-up makes him an easy target for bullying. Even though he's sweet and caring, Jerry is absolutely hopeless when it comes to his work. Somehow, Jerry ends up becoming the mayor of Pawnee, but we never see how that happens—most likely because it's by accident.
Creed Bratton
Although Creed Bratton technically executes quality assurance for Dunder Mifflin, he doesn't even work there. He can't remember his job title and spends most of his time playing games on the computer. Creed only goes to the office so he can get a paycheck and stay off the streets.
