Purpose: Organizations try to appoint individuals who fit in with their values and goals. Employees who do not fit in with the organization's core values and goals prefer not to stay on for a longer period of time. The present study is an attempt to explore the impact of person-job (P-J) fit on organizational commitment through job involvement and career commitment with an application of a serial multiple mediation model. Design/methodology/approach: Data have been collected through a structured questionnaire. The population comprised the teachers, working in the higher education sector. The different constructs used have been duly validated with the help of exploratory and confirmatory factor analyses. Further data reliability and scale validity have been checked too. In order to test the serial multiple mediation model, the authors adopted a regression-based approach and bootstrapping method suggested by Hayes (2012; 2013). Accordingly, PROCESS developed by Hayes (2012) has been used. Findings: The results revealed that job involvement and career commitment mediate the relationship between P-J fit and organizational commitment individually as well as together. Research limitations/implications: The present study is confined to government degree colleges only. The element of subjectivity might not have been checked completely as teachers have responded on the basis of their own experience and perceptions regarding the items in the questionnaire. The study is cross sectional in nature. Practical implications: The paper addresses the interest of wide spectrum of stakeholders including the management, organizations and employees. So, the authors have extended general implications, which are for all those organizations that want to improve person-organization (P-O) fit and commitment of their employees. These implications will help organizations to take specific initiatives to improve the P-J fit of their employees, which will subsequently enhance their commitment level. Originality/value: The findings of the present study will help the stakeholders in the higher education sector to identify best employees and undertake the initiatives to generate better job involvement and commitment, which will be a win-win strategy for both (employees as well as the organizations).
