Much of the success in these localities was due to the thoroughly systematic way in which the organizing work was carried on. This merits a brief description. There were two classes of organizers in the campaign, the floating and the stationary. Outside of a few traveling foreign speakers, the floating organizers were those sent in by the various international unions. They usually went about from point to point attending to their respective sections of the newly formed local unions, and giving such assistance to the general campaign as their other duties permitted. The stationary organizers consisted of A. F. of L. men, representatives of the United Mine Workers, and men hired directly by the National Committee. They acted as local organizing secretaries, and were the backbone of the working force. The floating organizers were controlled mostly by their international unions; the stationary organizers worked wholly under the direction of the National Committee. Everywhere the organizing system used was the same. The local secretary was in full charge. He had an office, which served as general headquarters. He circulated the National Committee's weekly bulletin, consisting of a short, trenchant trade-union argument in four languages. He built up the mass meetings, and controlled all applications for membership. At these mass meetings and in the offices all trades were signed up indiscriminately upon a uniform blank. But there was no "one big union" formed. The signed applications were merely stacked away until there was a considerable number. Then the representatives of all the trades were assembled and the applications distributed among them. Later these men set up their respective unions. Finally, the new unions were drawn up locally into informal central bodies, known as Iron and Steel Workers' councils. These were invaluable as they knit the movement together and strengthened the weaker unions. They also inculcated the indispensable conception of solidarity along industrial lines and prevented irresponsible strike action by over-zealous single trades.
