Labor Relations History

As labor unions and movements began to form and coalesce in the 19th century, the tensions between workers and companies led to demonstrations, encounters, and even conflicts that descended into violence. Among those, few were as notorious as the fight that took place on April 20, 1914 at Ludlow in the Southern Colorado coalfields between the Colorado National Guard and striking miners at a United Mine Workers camp. In the previous several decades, there had been a number of violent incidents during strikes, but in 1914, the Ludlow tragedy deeply shocked the nation.

On March 10, 1920, in Pachuca, Mexico, the Compañía de Santa Gertrudis may have committed murder. The alert was first raised at six in the morning: A fire was tearing through the El Bordo mine. After a brief evacuation, the mouths of the shafts were sealed. Company representatives hastened to assert that “no more than 10” men remained inside the mineshafts, and that all 10 were most certainly dead. Yet when the mine was opened six days later, the death toll was not 10 but 87. And there were seven survivors.

As labor unions and movements began to form and coalesce in the 19th century, the tensions between workers and companies led to demonstrations, encounters, and even conflicts that descended into violence. Among those, none were larger than the colloquially known Battle of Blair Mountain, which pitted West Virginian miners against authorities in 1921. It represented the largest labor uprising in American history and the largest armed uprising in the country since the Civil War, and it would have lasting ramifications on unions and labor moving forward.
