On May 10, 1986, the lives of thousands of working-class families changed abruptly when the federal government declared the Monterrey Iron and Steel Foundry, S.A. de C.V., bankrupt. This left the workers unemployed amidst one of the worst economic crises Mexico has ever faced. But the workers' identity did not disappear with the factory's closure. Its strong roots, cultivated from generation to generation, withstood the harsh blow of unemployment and, above all, the scorn they endured in the media. Thirty-five years later, the Acero Family, made up of former workers and their families, treasures and preserves its collective memory. This book presents the oral history of these former workers in order to recover and disseminate part of their legacy as social activists.
