IT IS apparent from the past history of the Negro worker that any advancement he achieves comes as a result of disequilibrium in the state of economic and political factors in society. At the end of the Civil War, not only in Chicago but in the country as a whole, very few job openings which had previously been held only by were made available to him. In Chicago the first real foothold in industry for the Negro was secured during the conflicts between packinghouse workers and operators in the late i890's when the Negro was introduced as a strikebreaker. The next major industrial opening followed in the early I900's, prior to World War I, at which time Negroes again acted as strikebreakers in the iron and steel industry, thereby securing relatively permanent employment for the years to follow. With the advent of World War I and with continuing industrial strife, the same procedure brought the Negro into the textile and garment industries. All three of these industries continued to employ the Negro in increasing numbers, but his opportunities for advancement beyond the unskilled level of occupations remained minute. The most the Negro could hope for were the undesirable traditional laboring jobs for which management and workers thought him particularly suited. Consequently, Negroes experienced more unemployment during the depression of the I930's than other groups, because, as common laborers, were the first ones to be discharged in great numbers. As business conditions improved and the defense program spurted ahead, those workers on relief or unemployed among the Negroes were gradually able to secure their old unskilled jobs with former employers, particularly in the three industries mentioned above. However, many industries were still reluctant to hire and employers in those industries expressed the usual reasons for not using Negro workers: whites and blacks cannot mix on the job, separate restrooms, locker-rooms, and workrooms would be necessary, making the introduction of Negroes too expensive and time consuming; are no trained Negroes available; they are racially unequipped for skilled work in industry; unions won't have them; or there was merely general dislike. In many cases the reasons were valid; but, as labor needs became more pressing and as the government took more decided measures to eliminate discrimination because of race or creed, reluctant employers found ways of integrating Negroes into their establishmpnts, and without serious difficulties. Although there was an increase in the total employment of Negroes during the war period in every branch of industry, there was a serious time lag both in the wider use of Negroes among many of the smaller individual firms and in the occupational upgrading of Negroes in all firms. This concentration of Negroes in a relatively few large firms, together with slow occupational progress generally, had the effect of restricting the use of Negro workers as a means of meeting immediate labor needs.
