The Union of South American Nations (UNASUR) could represent the cornerstone for working on "Forms of social protection for workers in the coming decades" in the American region, as it can set goals to solve the problem of the free transit of workers through different countries of the continent by means of a legal system of regional integration that allows for the development and social protection of the workers involved, generating jobs accompanied by social protection and security, through the design of social policies and regulations, in order to promote social and human development with equity and inclusion to eradicate poverty and overcome inequalities in the region. One of the basic and main objectives in this proposal for a common and integrating market is the free movement of people, as well as the free movement of goods, services and capital, for which it is necessary to eliminate the obstacles that workers may have to emigrate to another member country of the integration agreement.
