What challenges do you think garment workers faced in tenement sweatshops?

Injuries, little pay, no breaks, no bathrooms, you could stay there for more than like a whole day basically. Child labor, women would get their hair caught in machines an etc..

The document that stated that certain rights were not given by the government, but that men were born with them was the Declaration of Independence. This applied to all men and women equally. 

The articles of confederation and the U.S. Constitution also played a big role since they united the individual states and established the federal government. The national government and fundamental laws, guarantying the basic rights for the citizens respectively. 

I hope it helps, Regards.
