This study aims to explore the influence of organizational justice on employee thriving at work, with resilience acting as a mediating variable. The approach used was quantitative with a survey method. Data collection was conducted by distributing questionnaires to 102 civil servants at the Pasuruan City Environment, Sanitation, and Parks Office, using a non-probability sampling technique with saturated samples. 97 questionnaires were returned and could be analysed. Validity and reliability tests were conducted on 45 questions, resulting in 34 items being declared valid and reliable. Data analysis was conducted using the Structural Equation Modelling (SEM) method to examine the direct relationship between variables. The results of the analysis showed that organizational justice significantly and positively influenced resilience, as well as thriving at work. In addition, resilience was shown to partially mediate the relationship between organizational justice and thriving at work. These findings indicate that perceptions of justice in the organization can strengthen individual resilience, which in turn encourages increased thriving conditions in the workplace. Overall, the results of this study emphasize the importance of building a fair and supportive work environment to improve employee well-being and performance by strengthening resilience aspects.
