What tactic did the CIO use to improve labor conditions?

The sit-down strike was a significant tactic used by the Congress of Industrial Organizations (CIO) to improve labor conditions. This method involved workers occupying their workplace and refusing to leave until their demands were met, which effectively halted production and drew attention to their grievances. The sit-down strike was particularly impactful because it prevented management from replacing striking workers with scabs, thus allowing laborers to leverage their position more effectively.

This strategy not only increased the pressure on employers to negotiate but also galvanized public support for workers' rights. It highlighted the struggles of laborers for better working conditions, fair wages, and job security, and it played a critical role in the success of several labor movements during the early to mid-20th century. Through the effective use of sit-down strikes, the CIO was able to secure better contracts, organize more workers, and ultimately achieve significant improvements in labor conditions across various industries.
