The majority of social media studies have focused their attention on national and international companies in developed countries where democracy is part of the national culture of their citizens. The purpose of this research is to understand how social media usage effects organizational behaviour and culture in non-democratic countries. From a qualitative framework based on the current literature and Hofstede cultural analysis, we developed semi-structured interviews with one CEO and five middle managers from an international company in Iran in order to suggest several ways on how the use of social media within this type of company affects organizational behaviour. The results indicate that organizational culture is influenced by culture in nondemocratic countries. The use of social media also has a positive impact on transformational leadership, collaboration, knowledge sharing and team-work but negatively on transparency which increases organizational stress.
