The slogan "eight hours for sleep, eight hours for what we will" was promoted by the labor movement in the late 1800s, particularly by the American Federation of Labor (AFL) and other labor organizations. This campaign aimed to advocate for an eight-hour workday, emphasizing the need for workers to have time for rest, leisure, and personal pursuits outside of work. The movement sought to improve labor conditions and promote workers' rights during a time of industrialization and exploitation.
