The purpose of this research is to determine whether organizational virtuousness (OV) has a meaningful effect on work productivity (WP), to examine whether organizational justice (OJ) has an intermediate role on this effect and to determine the statistical difference of WP according to demographic factors. Accordingly, data has been obtained from 212 people working in the public and private sectors using a survey method. This data has been analyzed using the factor analysis, correlation, regression, Mann-Whitney U and Kruskal-Wallis H tests using SPSS and AMOS package programs. According to the findings obtained from the research; it has been determined that as a result of a multiple regression analysis on the mediating effect, OJ is a partial moderator variable on the effect of OV on the WP. As a result of the analysis to examine the differences, it has been found that WP did not show a significant difference according to monthly income levels and their durations of work experience. On the other hand, within this study, the WP has been higher than female employees, men working in the private sector, those working in the public sector, and those working in the 21-40 age group demographically, compared to those working in the 41-60 age group, and those who graduated from being undergraduates, compared to high school graduates.
