This research examines the connection between perceived organizational support and workplace spirituality in enhancing employee performance, with proactive attitude and employee engagement serving as mediating factors. Data were gathered by randomly administering questionnaires to 101 public sector employees in Indonesia, and the responses were subjected to analysis. Hypotheses were tested using structural equation modeling through AMOS version 26, with quantitative processing of the cross-sectional data. The results indicated a notable effect of perceived organizational support on proactive attitudes and overall employee performance, while proactive attitudes partially mediated the relationship between perceived organizational support and employee performance. Additionally, workplace spirituality demonstrated a significant positive impact on employee engagement and employee performance, with employee engagement acting as a mediator in the link between workplace spirituality and employee performance. The findings further revealed that both proactive attitude and employee engagement exert a substantial positive influence on employee performance. These outcomes could assist policymakers in government by emphasizing the value of fostering proactive attitudes and employee engagement to elevate performance levels within the public service sector. The study adds to the body of knowledge on human resource strategies that incorporate proactive attitudes and employee engagement as intermediaries in the effects of perceived organizational support and workplace spirituality on employee performance, particularly among Indonesian civil servants.
