Industrialization and urbanization: The late 1800s saw rapid industrialization and urbanization in the United States. This led to the growth of large factories and cities, which brought workers together in close proximity and made it easier for them to organize.
Poor working conditions: Industrialization also led to poor working conditions, including long hours, low wages, and dangerous working environments. These conditions motivated workers to organize in order to improve their待遇.
Rise of socialism and anarchism: The late 1800s also saw the rise of socialist and anarchist ideas in the United States. These ideologies emphasized the importance of collective action and worker solidarity, which contributed to the growth of the labor movement.
Government support: In the late 1800s, the federal government began to pass laws that protected the rights of workers to organize. This included the National Labor Relations Act of 1898, which made it illegal for employers to interfere with the formation of unions.
As a result of these factors, labor unions grew rapidly in the late 1800s. By 1900, there were over 2 million union members in the United States.
