Employee engagement involves employees putting discretionary effort into their work beyond what is required to complete tasks. An engaged employee is positive about their job, identifies with their organization, and works to improve performance. High commitment from employees can lead to high engagement, but engagement is possible without the highest levels of commitment, such as in knowledge work. Key elements that drive employee engagement include understanding one's role and how it contributes to organizational objectives, the work itself, leadership, opportunities for growth, and contributing to the organization. Strategies to improve engagement focus on developing a supportive work environment, opportunities for learning and growth, and performance management linked to rewards and recognition.
