International Printing Pressmen and Assistants' Union of North America
The International Printing Pressmen and Assistants' Union of North America (IPPU) was a labor union representing printing workers in the United States and Canada.By 1894, it had grown sufficiently that the ITU agreed to give the new union jurisdiction over pressroom workers, and to transfer its remaining members in the field.The union began accepting press feeders into membership, and in 1897, it adopted its final name.[1] In 1911, the union constructed its headquarters at Pressmen's Home, Tennessee, the site selected to also house a union-owned sanatorium and trade school.The trade school taught letterpress, but mostly focused on retraining workers in offset printing.
