ABSTRACT Quality of Work Life (QWL) has become one of the important topics in the last three decades. However, majority of previous studies focused on the QWL in developed countries. Few studies investigated QWL in developing countries in the manufacturing sector. The purpose of this study is investigating the QWL among workers in textile industry in the Jordanian qualified industrial zones (QIZs). Building on the literature, this study proposed that role overload, role conflict as independent variables (IVs) affect the QWL as dependent variable (DV). In addition, the study proposed that interactional justice will have a mediating role between the IVs and DV. The data was collected from 375 respondents working for 55 enterprises in 6 locations distributed in various QIZs. The findings of this study showed that role overload and role conflict has insignificant relationship with QWL of Jordanian workers in QIZs. The results also showed that role conflict have significant relationships with interactional justice. Future studies are recommended to replicate the findings of this study.
