The quantity of organizational citizenship behavior (OCB) that is displayed by the members of an organization is directly linked to the degree to which the organization is successful or unsuccessful. Being aware of the factors that greatly contribute to the development of this kind of mentality among workers is of the utmost importance for the sports sector. This is because of the reasons stated above. Although there have only been a few studies that have been conducted in depth on the issue, there is a large gap in the research that has been done on the subject of the influence of OCBs on employee performance in the sports industry. This is despite the fact that there have only been a few studies that have been examined in depth. This research was conducted with the intention of determining whether or not there is a correlation between organizational citizenship behavior (OCB) and performance in the sports industry in Nairobi County, Kenya. According to the findings of the study, factors that have an impact on productivity include being selfless and being pleasant to coworkers. Both of these factors were found to have an impact. It was also discovered that showing kindness to one's coworkers has an effect. According to the findings of the study that was carried out today, social exchange theory served as the foundation. An approach to study that is based on explanation was utilized all during the course of the examination. For the purpose of representing the Central Business District of Nairobi, seventy-four hundred and forty-eight individuals from twenty-five different sports were selected.
