How did the Industrial Revolution contribute to the growth of trade unions?

The Industrial Revolution was a primary catalyst for the growth of trade unions, as the transition from the domestic system to the factory system fundamentally altered the relationship between workers and employers.1

Under the factory system, workers lost the independence they previously held as craftsmen who owned their own tools and set their own hours. Instead, they were concentrated in large, often unsafe establishments where they faced long hours, low wages, and poor working conditions. As industrialization moved workers into new localities and created new jobs, traditional safeguards—such as customary rates of pay and individual bargaining—declined.12

These harsh conditions and the loss of individual bargaining power led workers to organize in an attempt to improve their circumstances through collective action. While early associations were often met with hostility from employers and governments—most notably through the Combination Acts, which made unionism illegal in Britain at the turn of the 19th century—the movement persisted. Ultimately, the necessity of collective bargaining became a defining feature of the industrial era, as workers sought to secure better pay, benefits, and working conditions in an increasingly mechanized economy.1234
