Sorry to send you guys a spitball, but here it is. You screwed up the name of the single most famous union in the history of the planet.
It is the Industrial - not the "International" - Workers of the World (IWW) (Interview, Socialist Review, July/August 2007).
The IWW gave you the term "Bread and Roses", the song Solidarity Forever, Joe Hill, the Little Red Songbook, Big Bill Hayward, the Red Scare, the Everett Massacre, pivotal free speech fights in Canada and the US, entire passages from the original post-revolutionary Mexican Constitution and Elizabeth Gurley Flynn.
It organised all around the world, from Chile to the massive labour uprisings of Australia to organising the first mixed race unions in South Africa at a time when the authoritarian Communist Party slogan was "Workers Unite for a White South Africa".
