The Knights of Labor railed against "wealth" in their Preamble, and planned to organize "every department of productive industry." The ultimate goal was establishing "co-operative institutions productive and distributive." The first principles of the order were organization, education, and cooperation. The Knights favored arbitration over strikes whenever employers and employees could find common ground. Although the Knights supported the eight-hour day in their constitution, the Knights' General Assembly failed to provide a plan for its implementation. Leadership of Knights considered a shorter workday impractical, and tried unsuccessfully to discourage their members from supporting the eight-hour movement. Because much of the platform of the Knights could be accomplished only through legislative action, the leadership consistently attempted to commit the organization to a political course. The membership was suspicious of the political aims of many of the leaders, who variously advocated Greenbackism, socialism, or land reform. Other issues favored by Terence V. Powderly, the Grand Master Workman of the order, were the abolition of child labor, and the establishment of producers' cooperatives. Organizers and the rank and file were more concerned with using strikes and boycotts to achieve higher wages.
