Many people think of employee engagement as a relatively new idea, but scientists have been studying it for years. William Kahn first introduced the term in 1990, defining it as “the degree of psychological identification employees experience with their job role or work persona.” He noticed that organizations tended to overlook the influence that everyday experiences have on people’s work motivation, focusing instead on their talents, skills, and expertise. Although such qualities are no doubt critical, they are not sufficient to account for the wide range of subjective experiences employees have at work.
