These days, it is not possible to accomplish tasks without having productive relationships with the rest of the world. Although there are some evidences, which indicate informal organizations normally face some limitations on their return but there are also some studies suggesting that informal organizations are the best ways for making significant changes. Recently, many people have suggested that informal organizations provide good infrastructures for organization's workflow many conflict of interests could be solved using informal communications. News can be distributed in organizations through informal units much easier and it is easier to handle them. In this paper, we investigate the relationship between informal communications with leadership style in some of governmental organizations located in free islands of Chabahar, in south east part of Iran. The proposed model of this paper designs a questionnaire and distributes it among many people who are acting as managers in those firms. The preliminary results indicate that there is a positive and meaningful relationship between leadership style and informal relationships.
