Entre embates e listas negras: lutas e experiências de trabalhadores da Coopagro por direitos em Toledo-PR (anos 1990 e início dos 2000)

This article analyzes the experiences and struggles of Coopagro workers in the context of the cooperative’s closure, with emphasis on employer coercion mechanisms, especially blacklists, used to limit access to the Labor Courts and to punish those who filed lawsuits. The Labor Courts are treated as a space of dispute, yet the documentation privileges strategies of exclusion and pressure. Grounded in Raymond Williams’ critical reassessment of the base-superstructure binomial, the analysis seeks to understand how workers acted and interpreted the contradictions generated by the crisis. Local newspapers are used as historical sources, examined from the perspective of Tania Regina de Luca. The study discusses the concept of Class Justice and denounces blacklists as a coercive strategy of the dominant classes. It concludes that, despite employer pressures, the workers found forms of resistance and affirmation of rights in western Paraná.
