Emily loves her job as a software developer. She looks forward to work each morning, excels in her endeavors, enjoys and admires her supportive team members, and is delighted with her working life. In contrast, Robert, a manager in a large accounting firm, despises his job. He trudges reluctantly to the office day after day, works halfheartedly, feels isolated from his colleagues, and knows deeply and with some desperation that his work life is devoid of meaning. Why is one employee so satisfied and performing well, and the other neither content nor productive? Why are some Emilies and Roberts of organizations flourishing and some floundering?
