Recent researches also indicate that Employee commitment and OCB are important parts and predictors of employee engagement in that commitment is conceptualized as positive attachment and willingness to exert energy for success of the organization, feeling proud of being a member of that organization and identifying oneself with it and OCB is a behaviour observed within the work context that demonstrates itself through taking innovative initiatives proactively seeking opportunities to contribute one’s best and going extra mile beyond employment contract. However, these constructs constitute the bigger construct employee engagement and they can not independently act as a replacement for engagement (Macey and Schneider, 2008; Robinson et al, 2004).
