Which movement aimed to improve labor conditions in the early 20th century?

The movement that aimed to improve labor conditions in the early 20th century is known as the Labor Movement. This movement emerged in response to the harsh working conditions, long hours, and low wages that many workers faced during the Industrial Revolution. It sought to advocate for workers' rights, including better pay, safer working environments, reasonable working hours, and the right to unionize.

Labor unions became a significant part of this movement, organizing workers to collectively bargain with employers for better conditions. The Labor Movement played a crucial role in establishing important labor laws, such as those governing minimum wage, child labor, and workplace safety, which have had a lasting impact on labor rights and standards in the workplace.

In contrast, while the other movements listed also aimed for societal improvements, they focused on different issues: the Civil Rights Movement was centered on racial equality, the Suffrage Movement focused on women's voting rights, and the Environmental Movement addresses ecological concerns. Each of these movements was significant in its own right, but none specifically targeted labor conditions in the way the Labor Movement did during that period.
