The beginning of the 21st century brought new reflections on work as an element of social inclusion and citizenship. The Industrial Revolution redefines working relationships by establishing a capitalist system of production which has led to job insecurity. Collective works, whether remunerated or unpaid, with the aim of maintaining jobs or creating new ones, then began to be considered and implemented within a different proposal from what is known as cooperative activity. Covering various productive sectors and involving the most diverse categories of workers, what these ventures presented in common was the structuring of the embryo of what is known today as a solidarity-based economy. The aim of this work is to analyse the challenges, difficulties and possible benefits of the solidarity-based economy as a field of economic practice, including the concept of social and environmental responsibility, fairness and fairness, by means of a case study carried out by the Bremen Agrolivestock Cooperativa de Brejo Grande in the municipality of Campos dos Goytacazes, in the state of Rio de Janeiro.
