Purpose: The main aim of the research is to investigate the relationships among primary school teachers' perceptions on coworker social loafing, organizational justice and task visibility. It is also examined whether teachers' opinions on organizational justice and task visibility are statistically significant predictors of their perceptions on coworker social loafing. Design/methodology/approach: Research was designed by using correlational survey model. The sample of the study consisted of 656 teachers selected by cluster sampling method among primary school teachers working in Eskisehir. Findings: Research results showed that teachers' perceptions on their coworkers' social loafing levels were low, while their perceptions on organizational justice and task visibility were high. Furthermore, it was determined that distributive justice and task visibility predicted 13% of teachers' perceptions about their coworkers' social loafing levels. According to this finding, as teachers' perceptions of distributive justice and task visibility increase, their perceptions about coworker social loafing decrease. Originality/value: This paper is unique in terms of examining the most probable antecedents of social loafing perceptions according to the literature among teachers which are organizational justice and task visibility together in Turkey context. The facts that social loafing studies are rare and hardly encountered among studies in the field of educational administration distinguish this study and make it appropriate to be published in a journal whose scope includes creation of an environment in which the management of resources provides the most efficient outputs.
