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.[1] 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.
