Explaining organization by industries rather than by trades, "The One Big Union Monthly," March 1, 1919, page 25, takes for instance the stockyards: "We do not know how many crafts there are in the stockyards, but there are many. According to the old style, these crafts would be organized each by itself, the carpenters belonging to the national union of carpenters, the engineers to the national union of engineers, the butchers to the national union of butchers, etc. It also belongs to old style unionism to leave the unskilled workers unorganized. Our method would be to organize all the workers in a plant, as a branch of the Stockyard Workers' Industrial Union. This would imply the cancelling of trade distinctions and craft lines. As against the employer we would face him not as butchers, laborers, carpenters or engineers, but as stockyard workers, no matter whether we are office clerks or laborers, or carpenters, or engineers. This is what we mean with industrial unionism. The various branches would combine into district organizations if necessary, and all of them together would form the Stockyard Workers' Industrial Union as part of the Industrial Workers of the World. By being thus organized we hope to be able to carry on the fight locally, or by districts, or on a national scale with better chance of success, than if we were split up in a great number of unions in each plant, with little or no contact with one another. The advantages of the one big union idea are so apparent that no honest worker will, in earnest, contradict us." The famous Preamble to the platform of the I. W. W. throws a startling light upon this revolutionary industrial union, which has, within recent years, been getting a very strong hold on immigrants from Europe: "The working class and the employing class have nothing in common. There can be no peace so long as hunger and want are found among millions of the working people, and the few who make up the employing class have all the good things of life. "Between these two classes a struggle must go on until the workers of the world organize as a class, take possession of the earth and the machinery of production and abolish the wage system. "We find that the centering of the management of industries into fewer hands makes the trade unions unable to cope with the ever-growing power of the employing class. "These conditions can be changed and the interests of the working class upheld only by an organization formed in such a way that all its members in any one industry, or in all industries if necessary, cease work whenever a strike or lockout is on in any department thereof, thus making an injury to one, an injury to all.
