Employee engagement in the corporate world, as well as in the academia, is an area of inquiry and exploration of its virtual importance. The objective of this research study is to present a conceptual model designed to probe the key antecedents and consequences of employee engagement, which determine the impact of empowering leadership, psychological capital, and job characteristics as antecedents, and employee service performance and organizational citizenship behavior as consequences related to employee engagement. This thesis replicates and expands Kahn‘s theory of engagement by integrating various variables designated as core antecedents and consequences of employee engagement. This research study is intended to contribute substantial knowledge to the argumentative literature on the employee engagement for academic researchers and business experts, which has mostly remained under the shadow of burnout concept based on Job Demand – Resource Model.

Empirical findings of the research study demonstrated positive and significant relationship among antecedents and consequences of employee engagement. Similarly, the results confirmed the partial mediation of employee engagement between aforementioned antecedents and consequences. Overall, this research study establishes and concludes that Kahn‘s theory of employee engagement is a sound conceptual basis for further research on this subject and guides future researchers to consider application of this theory for exploration of other relationships in the purview of employee engagement.
