The social responsibility of business has been discussed since the 50 s, from different approaches. In Brazil, however, the theme has only acquired strategic importance from the late 80 s onward. The evolution of the corporate social responsibility concept is presented,together with a study of the mobilization process of private companies towards social responsibility in Brazil. The main objective of the present research is to analyze corporate social responsibility in the Brazilian context, from a case study of a private company. The company s stakeholder relationship management process is investigated, with deeper approach to the company s relations with the community. A few company leaders and employees, program coordinators, and members of the community were inetrviewed. The main conclusions of the present research are that a company s social responsibility is a consequence of the values brought to the organizational culture by its leaders, along with external pressures of various natures. The possible benefits brought to the company as a result of its socially responsible behavior are also important factors. The studied company practices its social responsibility in a multidimensional way, having its values and principles reflected in its relationships with different stakeholder groups. However, some limitations are pointed out,especially in relation to the perpetuation of the current social responsible practices.The referred company could be classified as a - citizen company -, based on concepts proposed by different authors (Martinelli, 1997; Carroll 1998, 1999; Maignan, 1999,and Davenport, 2000).
