ABSTRACT:- This study focused on the relative influence of employees’ personal life and employees’ working time on employees’ performance in Nigeria’s Tier 1 banks. The study was a survey with questionnaire as the primary instrument. The study’s population was 392 permanent employees of studied banks in Akwa Ibom State of Nigeria. Applying Cochran’s sample size determination formular and Bowley’s model of proportionate distribution, a sample size of 269 was arrived for the study. The study achieved 74% response rate. Data were analyzed using simple linear regressions. Findings of the study showed that employees’ personal life (Beta = 0.496, t= 2,531 P< 0.05) and employees’ working time( Beta = 0.306, t= 2.807, P< 0.05) have significant influence on employees’ performance in Nigeria’s Tier 1 banks. Comparatively however, employees’ personal life was more influential in determining employees’ performance in Nigeria’s Tier 1 banks than employees’ working time. It was recommended that there was a need for a new thinking in banking that allows for employees of banks to pay more attention to aspects of their personal life to enhance full concentration that would translate to improved employee performance; it was also recommended that appropriate national legislations and policies be formulated to change banking practice to offer employees some control over their working hours including options for flexible and compressed works arrangement to make for balancing between employees’ work and non-work roles.
