Quizplus · Accepted Answer

The railroad industry was the first to face national labor issues, as the construction of the railroad system led to the development of national labor unions and strikes. The Great Railroad Strike of 1877, involving over 100,000 workers, marked a significant point in the history of the labor movement in the United States. While other industries such as oil, steel, and textiles also faced labor issues, they did so later and to a lesser extent compared to the railroad industry.
