The ascendancy of the American Federation of Labor during the 1890's reflected the poor working conditions in American society.

The formation of large labor unions, like the aforementioned American Federation of Labor, was a result of unfair treatment of their workers. During this industrial era, Americans worked anywhere between 80-100 hours a week and often worked 6 days a week. These workers also were paid very little in comparsion to what their bosses/the owners of the company were making.

Along with this, workers faced harsh and unsafe working conditions in industries like the mining industry. This resulted in workers coming together to fight for better working conditions, better pay, and less hours.
