The book "Organizational Citizenship Behaviour and Turnover Intention" by Michael Esop offers a comprehensive analysis of the factors influencing employee behavior in academic institutions. It specifically examines how organizational behavior and the intention to leave the organization are interconnected. By collecting data from 107 academic participants at the University of Papua New Guinea, a model is presented that considers various influencing factors such as distributive and procedural justice, affective and continuance commitment, as well as perceived organizational support. The results indicate that promoting organizational justice and support is crucial for reducing turnover intention and increasing employee engagement. This academic book is aimed at leaders and decision-makers in educational institutions who wish to develop strategies for improving the work environment and retaining employees.
