an injury to one is an injury to all

An injury to one is an injury to all is a motto popularly used by the Industrial Workers of the World. In his autobiography, Bill Haywood credited David C. Coates with suggesting a labor slogan for the IWW: an injury to one is an injury to all. The slogan has since been used by a number of labor organizations. The slogan reflects the fact that the IWW is "One Big Union" and organizes skilled and unskilled workers. Despite the reduced number of organized workers today, the slogan is still popular with labor unions and other organizations.
