Purpose - This paper aims to provide an overview of the recently introduced concept of work engagement. Design/methodology/approach - Qualitative and quantitative studies on work engagement are reviewed to uncover the manifestation of engagement, and reveal its antecedents and consequences. Findings - Work engagement can be defined as a state including vigor, dedication, and absorption. Job and personal resources are the main predictors of engagement; these resources gain their salience in the context of high job demands. Engaged workers are more creative, more productive, and more willing to go the extra mile. Originality/value - The findings of previous studies are integrated in an overall model that can be used to develop work engagement and advance career development in today's workplace.
