Employee engagement has been hotly debated among academics, practitioners and consultants, with each of them giving their own definitions of the concept. Though the consultants and the business press have carried out many studies, little is known about the antecedents and consequences of the concept in the academic literature. The construct of employee engagement is still evolving, and it is widely recognized that engaged employees do not quit the organization easily. It is also clear that some emotional and social competencies of employees have a significant positive relationship with employee engagement. This paper attempts to examine the role of employee engagement as a mediating variable in the relationship between employees' emotional and social competencies and their intention to quit. © Serials Publications.
