Emotional intelligence (EI) has been the highly discussed evolution since late 20th century. Around that time many organizations have started using EI as tools in measuring the employees' performances, and some organizations have incorporated EI in their employees' development program and some business schools have added EI training as part of their curriculum. However, despite this popular interest, there are still many questions of how exactly EI relates to task performance. In line with the growth of EI, Organizational citizenship behavior (OCB) has also sought its place in the research growing in popularity. With this popularity, statements regarding the importance of OCB in organizational effectiveness have been provided by many researchers. However, there are only a few empirical research emphasizing and addressing OCB with performance. This research will attempt to understand the role EI and OCB has in task performances of employees in an organization with organizational commitment (OC) as a moderator. Researches have shown a good data fit indicating the relationship between EI, OCB and OC, which will be further explored in this study.
