Violencia y trabajadores del petróleo / Violence and the oil workers

El presente artículo presenta resultados de investigación que pretende evidenciar la dramática situación de una región de Colombia que se ha convertido en uno de los escenarios de guerra, por parte de los grupos paramilitares, contra dirigentes, activistas sociales, militantes o disidentes políticos. Durante los últimos 25 años se han registrado alrededor de una centena de asesinatos de trabajadores petroleros vinculados a la Unión Sindical Obrera (USO) y para entender este fenómeno es necesario precisar el contexto histórico y señalar cómo surgió y se expandió el paramilitarismo por el Magdalena Medio desde comienzos de la década de 1980, financiados y auspiciados por distintos sectores de la sociedad colombiana. Es necesario recalcar que el ataque contra los sindicalistas es un crimen de “lesa humanidad”, tanto en Colombia como en el resto del mundo.
