The day has gone by for the efforts of isolated trades [wrote H. M. Hyndman]. Nothing is to be gained for the workers as a class without the complete organization of labourers of all grades, skilled and unskilled.... We appeal ... to the skilled artisans of all trades ... to make common cause with their unskilled brethren and with us Social Democrats so that the workers may themselves take hold of the means of production and organize a coöperative commonwealth....[34] What is even more significant in view of the present day I. W. W. demand for industrial control is the fact that there was constantly cropping up in the eighties the Owenite demand that the workers must be allowed to "own their own factories and decide by vote who their managers and foremen shall be."[35] In 1888 came the famous Haymarket riots in Chicago. The effect of this tragedy was unquestionably to give the labor and socialist movements a serious setback. The labor movement [says Robert Hunter] lay stunned after its brief flirtation with anarchy. The union men drew away from the anarchist agitators, and, taking their information from the capitalist press only, concluded that socialism and anarchism were the same thing, and would, if tolerated, lead the movement to ruin and disaster. Without a doubt, the bomb in Chicago put back the labor movement for years. It ... did more to induce the rank and file of trade unionists to reject all association with revolutionary ideas than perhaps all other things put together.[36] Justus Ebert, who is now a member of the I. W. W., declares that the Haymarket affair "involved the new Socialist Labor party in a fierce discussion of the right course to pursue in the emancipation of labor."[37] Robert Hunter thinks that these riots really gave the French unionists the idea of the General Strike and thus helped to give form, first, to modern French syndicalism, and second, both by relay back to this side of the Atlantic and directly by its influence in this country, to American syndicalism in the form of the Industrial Workers of the World.[38] Five years after Haymarket--in June, 1893--an industrial union of railway employees was organized in Chicago by Eugene V. Debs. A year later, at the time of the Pullman strike, it had a membership of 150,000. The failure of that strike, which by the way was an early example of I. W. W. tactics, broke down the union, and it passed out of existence in 1897.
