Background and Purpose: This study examines reward system, job satisfaction, and job performance among Bangladeshi banking executives. The banking sector's huge contribution to the economy makes it crucial for organization’s effectiveness and employee well-being to understand these links. Design/Methodology/Approach: In Dhaka, Bangladesh's capital, 210 bank officials from various departments were questioned for data collection. Surveys were delivered via email and in-person using convenience and purposive sampling methods. Smart PLS 4 and IBM SPSS version 27 were used to analyze the data using partial least squares-based structural equation modelling (PLS-SEM). Results: The reward system has a significant positive connection with job satisfaction, suggesting that employers believe rewards affect employee pleasure. However, a statistically significant adverse relationship was found between the reward system and job performance, suggesting that rewards may not instantly boost performance. In addition, job pleasure mediates the reward system-job performance relationship. This shows how job pleasure affects employee productivity through organizational rewards. Conclusion: Although it provides unique insights into Bangladesh's banking industry's reward system, job satisfaction, and job performance, this study's small sample size and cross-sectional design limit it. Future research may include longitudinal, qualitative, comparative, intervention, and mediator and moderator studies to further understand their interconnections. In general, this study shows that combining organizational rewards with employee pleasure creates a job environment that promotes good performance and company success.
