Objective: This study aimed to model the impact of compensation satisfaction on job satisfaction and future hope, considering the mediating role of perceived justice among employees of the Khorasan Razavi Regional Water Company.

Method: The present study was applied in purpose and survey-analytical in method. The statistical population consisted of all 400 employees of the company. Using Cochran's formula and simple random sampling, a sample of 196 individuals was selected. Data were analyzed using SPSS and Smart-PLS software.

Findings: The results indicated that compensation satisfaction has a positive and significant effect on both job satisfaction and future hope. Furthermore, perceived justice not only has a direct positive effect on these two variables but also acts as a mediating variable in the relationship between compensation satisfaction and job satisfaction/future hope.

Conclusion: The findings emphasize the importance of designing fair and transparent compensation systems in public organizations. Enhancing compensation satisfaction, by strengthening the perception of justice, can lead to improved job satisfaction and employees' optimism about the future. Therefore, managers should establish performance-based and equitable reward systems to foster increased productivity and organizational commitment.
