Abstract

This study investigated the role of age, job experience and abusive supervision in predicting the organisational commitment of selected hospital staff in Owerri. One hundred and twenty-seven participants were selected from eight hospitals in the city of Owerri for the purpose of this study using convenient sampling technique. The participants’ ages ranged from 25 to 45 with a mean age of 32.25 and Standard Deviation of 6.56. Two instruments employed in the study were the Abusive Supervision Scale by Tepper (2000) and the Organisational Commitment Questionnaire (OCQ) by Allen and Meyer (1993). The cross-sectional survey design was adopted for data collection while the hierarchical multiple regression analysis was used for analysing data. The findings indicated that age and job experience were not significant predictors of organisational commitment among hospital staff in Owerri. On the other hand, the results demonstrated that abusive supervision had a significant negative relationship with organisational commitment among hospital staff in Owerri. The results suggest that abusive supervision has a more significant impact on employees' organisational commitment than age or job experience among hospital staff in Owerri. This indicates that when employees perceive their supervisors to be engaging in abusive behaviours towards them, they are less likely to be committed to their organisation. This highlights the importance of addressing and preventing abusive behaviours by superiors in the workplace to improve employees' commitment to their organisation.
