Organizational citizenship behavior (OCB) can improve organizational effectiveness. Individual altruism and commitment to the organization are at the core of OCB. This study aimed to examine the impact of organizational commitment and demographic factors on OCB in the Malaysian financial sector. The cross-sectional study targeted 280 employees from diverse backgrounds and positions across banking and non-banking financial institutions following conventional as well as Islamic Sharia principles in Malaysia. The respondents include individuals from management levels (upper management, middle management, non-management) and divisions (finance, operations, retail/corporate banking, and others). Data analysis included multiple regression analysis and ANOVA. The findings reveal a complex interaction where organizational and normative commitment do not significantly predict OCB, while affective commitment shows a significant positive correlation with OCB. The study revealed that employees with higher emotional attachment to their organization exhibit more OCB (r = 0.155, p < 0.009). In addition, demographic factors, such as education (r = 0.025, p < 0.067), age (r = 0017, p < 0.003), tenure (r = 0.107, p < 0.003), and management level (r = 0.17, p < 0.004) emerge as positive influencers of OCB. Thus, higher education levels, older employees, longer tenure, and managerial positions are linked to higher levels of OCB. At the same time, no significant gender-based differences are observed in employees’ OCB. The findings imply that organizations should emphasize building emotional connections with employees through supportive leadership and a positive work environment to enhance organizational effectiveness.
