How can managers and executives motivate workers to make them happier and more productive? How can employees find meaning and motivation in their careers? The classic Two Factor Theory—a simple, time-tested model for conceptualizing job satisfaction—is here re-imagined for a modern world, with relevant examples, and backed by dozens of academic studies that organizational leaders can draw upon to improve worker motivation. The Universal Dual-Factor Survey (UDS) is introduced, providing a means to assess workforce job satisfaction. Managers will be able to understand which factors need improvement, leading to more meaningful work. Employees, at all levels of business, government and nonprofit organizations, will be able to improve personal motivation, facilitating a more cohesive and thriving workforce.
