How did John Jacob Astor treat his workers poorly?

John Jacob Astor, a prominent American fur trader and businessman in the early 19th century, was known for exploiting his workers, particularly in the fur trade. He often paid them low wages and subjected them to harsh working conditions, including long hours and physically demanding labor. Many workers faced significant risks in their roles, such as exposure to extreme weather and dangerous wildlife, while Astor prioritized profit over their well-being. Additionally, he frequently employed a system that favored his interests, leaving workers with little recourse for improving their situations.
