John Graham Brooks,
American Syndicalism
(1913)
“ The Knights of Labor were less ambitious. They created an organization which lent itself to new uses of the boycott and the "sympathetic" strike. This sweeps together widely different unions into a common revolt. There was much eloquence expended upon its possibilities. The "sympathetic strike" was but a fine practical illustration of their noble motto: "An injury to one is the injury to all." ”
