Dentro del movimiento obrero (Inside the Labor Movement) [PDF ebook] 

It”s difficult for many young people to imagine not being able to go to school and instead having to work in a hot, smelly, sometimes dangerous factory for more than 12 hours a day. There was a time in U.S. history when young people had to do just that. Thankfully, many people involved in the labor movement fought against child labor. This was just one of many ways the movement improved rights for working people. This important volume presents a significant slice of American history, using primary sources, first-person narratives, and historical photographs to enlighten readers.
