This research examines how the Brazilian State, from the post-30s onwards, with its peak in the New State period, implemented a citizenship project based on the labour movement and how it was affected with the emergence of the Labour Reform. The argument focuses on how the labour movement as a project, represented by a political ideology coined in concessions by the State, embodied with the promulgation of the Labour Laws and gradually built by state policies, was relaxed. This rupture process took place through a thorough reform of social legislation, which denied and removed labour rights, through the enactment of several laws starting in 2017, such as Law N° 13.429 / 2017 and Law N° 13.467 / 2017. In order to support this proposition, further investigation is conducted on the implementation, maintenance and dismantling of this political project called labour movement, as well as its repercussions for the configuration of the State, its relationship with the people and with the citizenship in Brazil.
