Which was a major achievement of both the Knights of Labor and the American Federation of Labor during the late 1800s and early 1900s?

Both the Knights of Labor and the American Federation of Labor supported shorter working hours, including the campaign for an eight-hour workday. Reducing the workday from ten hours to eight was therefore a shared labor achievement. Neither organization ended strikes, and hiring skilled workers or expanding the labor force were not their main shared goals.
