<![CDATA[Nursing staff are a key component of hospital services and play an important role in maintaining service quality and patient safety. However, high work demands that are not balanced with adequate rewards can lead to effort–reward imbalance, which may reduce employee engagement and organizational citizenship behavior (OCB). In addition, the level of work compliance is an important factor in supporting positive work behavior in the hospital environment. This study aims to analyze the effect of effort–reward imbalance and work compliance on OCB with employee engagement as an intervening variable among nursing staff at Sukabumi Class C Hospital. This study employed a quantitative design with a survey approach. The study population consisted of nursing staff at Sukabumi Class C Hospital, and the sampling technique used was the census method. Data were collected through structured questionnaires. Data analysis was conducted using Structural Equation Modeling–Partial Least Square (SEM-PLS). The results showed that effort–reward imbalance and work compliance had a significant effect on employee engagement and organizational citizenship behavior. In addition, employee engagement was found to have a positive effect on OCB and was able to mediate the relationship between effort–reward imbalance and work compliance with OCB.Conclusion. The balance between effort and rewards, as well as a good level of work compliance, can enhance employee engagement, which in turn encourages the emergence of OCB among nursing staff. Hospital management should improve the reward system, strengthen the culture of work compliance, and create a work environment that supports nurse engagement in order to enhance OCB and improve the quality of hospital services.]]>
