This Master´s Degree Dissertation presents bibliographical analysis on the subject cooperativism and a case study of the Cooperative of Work composed for furniture makers and woodworkers from the city Guajará- Mirim, RO. Our objective was to verify the possibilities and limits that the organization of workers through a Cooperative of Work can offer for their emancipation. To make this analysis we took for base principles and values that guide the cooperativism, such as, solidarity, mutual help and cooperation among its members. Considering the reality that we live in Brazil from the decade of 1990, the cooperatives of work have been multiplying themselves, have been inserted in the process of terceirização of companies, adapting themselves to the transformations guided by neoliberal ideals, that, paradoxically, spread out individualism and the competition as values. It is therefore, in this context that we try to reveal the meaning of the work in the Cooperative of furniture makers in Guajará- Mirim.
