ABSTRACT
In many industries, the development of a worker's potentiality is contingent on advancement to work in which the level of skill and responsibility provides more challenge than the more numerous production jobs. While supervisory positions, self-employment, or a career in the union are available for a few, for most manual workers promotion means the upgrading of skill, status, job grade, and wages within the ranks of blue-collar work. Advancement to more skilled and responsible work is not therefore as important an element in the development of the printer's potentialities as it is for a semiskilled worker. The textile industry restricts the development of its employees' potential because of its limited opportunities for advancement. A fourth factor which influences integration in the chemical industry is its status structure. The technological requirements of continuous-process production encourage a finely elaborated status structure, a balanced skill distribution emerges, made up of employees at all levels of training and responsibility.
