This paper aims to investigate the role of Employee Spirituality to moderate between Compensation fairness and Employee Engagement, Job involvement and Employee Engagement, organizational commitment, and employee engagement. In this survey, 279 respondents were collected with a 75 percent response rate (139 respondents) from May to July 2020 and a 93.3 percent rate (140 questionnaires) from August until September 2020. Validity used Confirmatory Factor Analysis used KMO and Bartlett’s test, and the reliability test was based on Cronbach-Alpha. Moreover, Kolmogorov-Smirnov test is used for normality test, Park test is implemented for Heteroscedasticity and Multicollinearity test. Moderator Regression Analysis is used to identify the moderator types. The results indicate that Employee Spirituality fully moderated (Pure moderator) between Compensation fairness and Employee Engagement and between Organizational Commitment and Employee Engagement. Moreover, Employee Spirituality partially moderated between Job Involvement and Employee Engagement. The research suggests to implement the model in a narrow scope and considers many variables outside the Compensation fairness, Job Involvement, and Organizational Commitment.
