When did conditions for workers in industrialized nations begin to improve?

Conditions for workers in industrialized nations began to improve significantly during the late 19th and early 20th centuries, particularly through the efforts of labor movements and the establishment of trade unions. Key reforms, such as the introduction of labor laws, improved workplace safety, and the establishment of minimum wage standards, gained traction during this period. The aftermath of World War II also played a crucial role, as economic growth and social policies led to better working conditions and benefits in many countries. By the mid-20th century, many workers in industrialized nations experienced substantial improvements in their rights and living standards.
