Definition
The labor movement is the organized struggle of working people to secure better wages, safer conditions, shorter hours, and legal rights. It took shape most strongly during industrialization, when large numbers of wage workers in factories, mines, and railways shared common grievances.
Its main vehicles are trade unions — associations of workers in a trade or industry — along with broader political parties, mutual-aid societies, and reform campaigns aligned with workers' interests.
Why it matters
How it works
The core logic of the labor movement is that a single worker has little bargaining power against an employer, but workers acting together can negotiate as a bloc and, if necessary, withhold their labor through strikes. Unions organize workers, negotiate collective agreements, and lobby for protective laws. Over time the movement won landmark changes — restrictions on child labor, the eight-hour day, the right to organize. It also faced fierce resistance and internal divisions, including debates over which workers to include. Studying it shows how economic change generates pressure for political and legal reform.
