In its early years, Armour sold every kind of consumer product made from animals: meats, glue, oil, fertilizer, hairbrushes, buttons, oleomargarine, and drugs, made from slaughterhouse byproducts. Armour operated in an environment without labor unions, health inspections, or government regulation. Accidents were commonplace. Armour was notorious for the low pay it offered its line workers. It fought unionization by banning known union activists and breaking strikes in 1904 and 1921 by employing African Americans and new immigrants as strikebreakers. The company did not become fully unionized until the late 1930s when the meatpacking union succeeded in creating an interracial industrial union as part of the Congress of Industrial Organizations.
