It is apparent that since the war has put a stop to the importation of foreign immigrants, the Negroes are so far the only cheap and unorganized labor supply obtainable. Indeed Mexicans were brought to work here in the same way, although the experience with them was not as satisfactory as with the blacks. While it may be true that the motive for bringing these ignorant workers is primarily to fill up the unskilled labor gap, and not to break up the labor movement, it is self-evident that the employers would scarcely admit the latter motive even though it was paramount. It may be, that ultimately the employers may use these workers against the union organizations or against the securing of the eight-hour-day, which the local unions are aiming to attain. Indeed, the employment agent of one of our great industrial plants, which underwent a big strike a few years ago, pointed out that one of the great values of the Negro migration lies in the fact that it gives him a chance to “mix up his labor forces and to establish a balance of power”, as the Negro, he claimed, “is more individualistic, does not like to group and does not follow a leader, as readily as some foreigners do.” However, in only one instance in our survey of the Pittsburgh Trade Unions, was a complaint lodged against colored people taking the places of striking white workers. This was in a waiters’ strike and was won just the same, because the patrons of the restaurants protested against the substitution of Negro waiters. In all the others, there were no such occurrences. Indeed, the number of Negroes taking the places of striking whites and of skilled white workers is so small that it is hardly appreciable. They are, as we have seen, largely taking the places which were left vacant by the unskilled foreign laborers since the beginning of the war, and the new places created by the present industrial boom. No effective effort has been made to organize these unskilled laborers by the recognized American labor movement. These people, therefore, whose places are now being taken by the Negroes, worked under no American standard of labor, and the fear of these unskilled laborers breaking down labor standards which have never
