Employee engagement refers to the level of commitment and involvement an employee has towards their organization. It was first defined by William Kahn as the harnessing of an employee's self to their work role. Engaged employees are fully absorbed in and enthusiastic about their work and take positive actions to further the organization's interests. High employee engagement is linked to increased productivity, better performance, and lower turnover. It is measured using validated surveys that assess factors like an employee's engagement with the organization, their work, and their workplace.
