Organizational support has become an increasingly important issue for organizations to become more productive and reaching targets. Members of the organization provide a significant contribution to the extent they feel they are supported by their organizations. However, an organization member who thinks that organizational support has been provided is one step ahead of their work. Organizational citizenship behavior (OCB) covers a number of factors based on voluntary but non-compulsory behaviors and attitudes of the organization's members. Whether the organizational support that employees perceive affects organizational citizenship behavior or not is subject worth to study. This study on the relationship between organizational citizenship behavior with its dimensions and perceived organizational support was revealed by a survey among glass factory employees operating in Ankara. In the study conducted, it was concluded that there is a positive relationship between organizational citizenship behaviors and perceived organizational support. In this context, as the perceptions of organizational support increase, the exhibitions of organizational citizenship behaviors towards the organization and individual also increase.
