Labor movements are organized efforts by workers to improve their rights and working conditions. These movements often focus on issues like fair wages, safe workplaces, and reasonable working hours. By coming together, workers can negotiate better terms with their employers, often through unions, which are groups that represent workers' interests. Throughout history, labor movements have played a crucial role in shaping laws and policies. For example, the American Federation of Labor and the International Labour Organization have been instrumental in advocating for workers' rights. These movements have led to significant changes, such as the establishment of the 40-hour workweek and child labor laws.
