Final answer:
The Knights of Labor and the American Federation of Labor aimed to negotiate for increased wages, improved working conditions, and shorter workdays; contrary to expanding child labor, they worked to restrict it.
Step-by-step explanation:
Labor unions, such as the Knights of Labor and the American Federation of Labor (AFL), formed to negotiate for better working conditions for laborers during the industrial era. Mainly, they focused on advocating for:
- Increased wages
- Improved working conditions
- Shorter workdays
These goals reflect the unions' broader mission to improve the economic and social well-being of workers. They used strategies like collective bargaining and strikes to leverage their demands and secure these workplace reforms. Notably, the goal to expand child labor is not correct; labor unions sought to end or limit child labor, not expand it.
