The purpose of this paper is to examine the impact of quality of work life (QWL) on organizational citizenship behaviour (OCB) of employees. Also, the paper examines the role of demographic variables, i.e. gender, position and type of organization as moderators of relationship between QWL and OCB. Design/methodology/approach: A survey with sample of 375 was used in this study. PROCESS tool by Hayes (2013) was used to analyze the relation between QWL, OCB and demographic variables. Findings: QWL was found to positively influence OCB. Gender and type of organization were found to moderate the relationship, whereas position failed to moderate the relation significantly. Practical implications: The study reinforced the significance of QWL practices by organizations to improve extra-role behaviours of employees. Also, importance of considering gender and the industry you are in is emphasized in using and designing the QWL programme for employees. Originality/value: While many antecedents have been studied in relation to OCB, QWL is rarely discussed. The paper attempts to reemphasize QWL’s importance in doing so in light of demographic variables as moderators.
