This paper seeks to investigate the direct influence of interactional justice dimensions—specifically informational and interpersonal justice—on various aspects of organizational cynicism (cognitive, affective, and behavioral).Drawing from existing literature, an analytical model was developed to examine the relationships between the research variables. Primary data was collected using a questionnaire administered to 325 employees of the Egyptian Tax Authority in Dakahlia Governorate. A stratified probability sampling method was employed to achieve the research objectives, and data analysis was performed using SPSS V.25 for descriptive analysis and structural equation modeling (SEM) with AMOS software, along with path analysis to test the research hypotheses. The findings reveal a significant and negative direct impact of informational justice on all dimensions of organizational cynicism. Furthermore, the results show that interpersonal justice also has a significant and negative direct effect on all aspects of organizational cynicism (cognitive, affective, and behavioral) among employees of the Egyptian Tax Authority.
