The aim of this article is to discuss the impact on identities and the dynamics resulting from them, starting with different forms of insertion in the world of work; more specifically, beginning with the informal sector workers' socialisation and their cooperatives. Therefore, we consider the following elements underlined: workers in the informal sector who earn from one to three minimum wages; workers in cooperatives who earn the same amount; some concepts to understand identity at work and, finally, ties among those elements that help to perceive changes produced in the world of work itself.
