Os retornados: reflexões sobre condições sociais e sobrevivência de trabalhadores rurais migrantes escravizados no tempo presente Cristiana Costa da Rocha Historia Trabalho escravo migração e retorno O artigo é dedicado ao estudo de trabalhadores rurais de Barras, Piauí, que migram repetidas vezes para os estados do Pará, Mato Grosso e Goiás e vivenciam formas de trabalho análogo à escravidão. Após um longo período do ano longe de casa, eles chegam cheios de notícias sobre o trabalho duro e a exploração, o pouco salário, as ilusões, as agruras, o engodo praticado pelos empreiteiros, sobre o que os faz ter vontade de voltar para o seu mundo. E, passado o período da entressafra, partem novamente, vestidos em suas melhores roupas como em um dia de festa, imbuídos pelo desejo de materializar sonhos, maravilhados por um mundo cujos perigos lhes impõem desafios. 2012 artículo científico 0102-0188 https://www.redalyc.org/articulo.oa?id=26325224009 pt http://www.redalyc.org/revista.oa?id=263 Revista Brasileira de História application/pdf Associação Nacional de História Revista Brasileira de História (Brasil) Num.64 Vol.32
