What are the differences between workaholism and work engagement in IT-enabling and highly-competing era?

Workaholism and work engagement both imply high involvement with work, a similarity that has led to some conceptual confusion. Although workaholism differs in important ways from work engagement, few studies investigate that distinction. This study applies the job demands-resources (JD-R) model of work engagement to workaholism and proposes an integrative workaholism model to demonstrate the conceptual and theoretical dissimilarity between workaholism and work engagement. It first demonstrates that job demands are positively related to workaholism. Second, job resources moderate the relationship between job demands and workaholism. Third, personal resources/ psychological capital moderate the relationship between job demands and workaholism. Finally, workaholism is negatively related to job performance.
