The present dissertation takes as field a state school located in a neighborhood in Rio de Janeiro, that has undergone changes related to the urban conflicts in recent years. As the school is attended by local students and teachers, the research aimed at investigation and understanding through narrative and positioning constructions (Bamberg, 1997; 2002) of teachers / residents, how they construct their identities as public school teachers in a periphery and how they deal with the challenges of violence and position themselves in relation to circulating discourses on education and violence. The study is therefore qualitative and interpretative (Denzin e Lincoln, 2006), and proposes an analysis of autoethnographic bias, since its author is also part of the school faculty. The data presented in this research were generated in the interactions in semi-structured qualitative interviews and audio recorded (Mishler, 1986; De Fina, 2009). In addition, all interviews in this study are analyzed with theoretical perspective support in Narrative Analysis (Labov e Waletzky, 1967; Labov, 1972; Riessman, 2008; Bastos e Biar, 2015), more specifically in the conception of non-canonical, micronarratives (Bamberg e Georgakopoulou, 2008) and life stories (Linde, 1993), focusing on life experiences and micropositioning interface with macrodiscourses. The research also presents as an analytical support the reflections and notions of Bamberg (2015), Bamberg and Georgakopoulou (2008) and Freeman (2010) on identity construction, Goffman (1963) on social stigma and Ewick and Silbey (2003) on resistance. The analysis show that: i) in the interaction, the narrators present themselves as teachers who are resistant to the current difficulties imposed by the violence in the school environment, because they have already undergone challenges before and during the academic admission, as these professionals are marked by life stories of resistance and overcoming; ii) the narrators present identificational positionings that are related to their students and the teachers, with whom they have studied and who are taken back as inspiration; iii) teachers face their profession as a social role and violence in the neighborhood as a neglect of public policies; iv) teachers are reflective about their professional and life choices, as very active agents in the school community, while they oppose pedagogically violence and drug trafficking, that attempts to corrupt students on a daily basis.
