In the present work we analyze a case that puts its focus, with a narrative, interpretive and reflective method, on events of two cooperative teachers, grade teachers, who invoke Acquired Rights based on situations resulting from the call made from the Ministry of Culture and Education of the Province of Formosa-Argentina - from the year of 1996 to the present day-. It examines the pecularity of the tension arising from the change of the Constitutional Law of teaching and learning cooperativism, inseparable from the performance and professional responsibility of educators, as an expression of the doctrine that highlights the relationship between individual and social rights, for example. In this context, the Law of Public Advocacy and Cooperative Law are interwoven in a friendly manner in Labor Law.
