Why was there a need for labour unions in America during the gilded age?

During the Gilded Age, the rapid industrialization and urbanization in America led to harsh working conditions, long hours, and low wages for laborers. Workers faced exploitation and lacked job security, prompting the need for collective bargaining power. Labor unions emerged to advocate for workers' rights, improve working conditions, and promote fair wages, providing a unified voice against the growing power of industrialists. This period marked a significant shift as workers sought to organize and demand better treatment in a rapidly changing economy.
