The Moderation Effect of Age on the Influence of Shift Work Practices on Organizational Citizenship Behaviour of Medics in Tanzania’s Government Hospitals

Abstract

This study examines the moderation effect of age on the influence of Shift Work Practices on the dimensions of organisational citizenship behaviours (OCB). Data were collected from 330 randomly-selected medics working in Tanzania’s government hospitals. Results from the analysis conducted using Structural Equation Modelling with AMOS indicate statistically significant direct effects of shift work practices on all the three dimensions of OCB namely, conscientiousness, sportsmanship and civic virtue. Results also show that age significantly moderates the influence of shift-work practices on sportsmanship and civic virtue. The findings imply that how shift-work practices influence OCB behaviours isn't straightforward — it changes depending on the age of the employee. This suggests that managers of government hospitals need to consider employees’ age in designing shift works to enhance employees’ OCB and subsequently service quality.
