The primary objective of the study was to scrutinize the influence of leadership styles on organizational management, focusing on a case study of First Bank in Abuja Metropolis. Primary data sources were employed in the research. The study utilized a survey research design, and the Smart-PLS Regression technique was employed for data analysis. The findings of the study indicated that democratic, autocratic, and laissez-faire leadership styles had a positive and statistically significant impact on the performance of First Bank employees in the Abuja metropolis. Consequently, the study concluded that leadership style exerted a significant influence on the performance of employees in the selected Nigerian bank. The study recommended that organizations should adopt a democratic style of leadership and human management practices to encourage workforce commitment to their duties. While the study recognized that an authoritative leadership style bolsters performance, it was suggested that the organization should elucidate expectations and provide goals and standards to be achieved by the staff. The laissez-faire leadership style was proposed for adoption across all banks as it fosters visionary employees, provides freedom from interference, and simultaneously motivates employees with a high sense of responsibility.
