This paper aims to analyze the changes in the different forms of labour recruitment of the corteros, backed by legal initiatives, which have affected precarization, labor outsourcing and the workers´ group fragmentation. As well as the conflicts of the first decade of the 2000: the 2005 and 2008 strikes that resulted in changes of the sugar industry in general and in particular in the sugar refineries. Adherence to the Global Compact and the subsequent publication of annual sustainability reports guided on the principles of the Global Reporting Initiave, marked a new form of relationship between workers and employers. This adhesion also implied the overhaul of old personalized and arbitrary social aid, managed by the employer and the church; the installation of new areas of social welfare within the sugar refineries; and the consequent reorganization of the relationship of the employers with their collaborators, suppliers, shareholders and the community. In this context, we aimed to answer: how does corporate social responsibility work in a context of high levels of labor outsourcing?
