The workplace environment keeps on changing, indicating its dynamic nature as well as unpredictability. Organizations require its employees to be more committed as well as to have a better cohesive working interrelationship. Emotional intelligence (EI) and spiritual Intelligence (SI) are the most important concepts introduced to psychology and management in the last decade and individual job performance (JP) is highly important for an organization. Hence, there is a need to identify the influence of EI and SI on JP. In addition to that only few studies so far have been conducted to explore impact of EI and SI on JP of employees which show an empirical knowledge gap. Hence, the main aim of this study is to emphasize the impact of EI and SI on JP of employee. In this study EI and SI are independent variables and JP as dependent variable. EI has four dimensions and SI has three dimensions. A cross-sectional survey using structured questionnaire was used to collect data from to 165 employees in selected Commercial Banks in Nuwara-Eliya District and all the items in the independent and dependent variables were tested through reliability test to ensure the consistency of the scale. Univariate analysis was carried out and the results show employees have high level of contribution of EI and SI to determine the JP. The correlational analysis was carried out and the result indicated there was a medium positive relationship between SI and EI, EI and JP and also SI and JP. The multi linear regression analysis was carried out and the results revealed that EI and SI significantly and positively impact on JP of employees.
