In the current educational reform climate, teacher training is being intensely scrutinized by policy makers, the general public, and teachers clamoring for increased training in the practical aspects of teaching. This booklet examines the labor organization's role in its members' job-related training. Although unions have historically played a major role in their members' knowledge and skill development, no comprehensive or authoritative information sources on training programs with union involvement exist. The study summarized here attempts to rectify this situation by examining apprenticeship programs conducted under the auspices of the Bureau of Apprenticeship and Training (BAT), the Department of Labor agency responsible for the administration and technical support of programs meeting federal standards. Journeyman upgrading programs are also investigated, along with the Air Line Pilots Association's involvement in training and evaluation. Study results indicate that union training programs and union involvement in issues around training serve to further the collective interests of individual unions' members. Apprenticeship and other training programs help unions: (1) define their respective crafts; (2) adapt to trade changes; (3) ensure maximum employability of their members; (4) ensure workers' skill consistency; and (5) tie increases in compensation to increases in skills. Intermediary government agencies do not necessarily eliminate unions' training and evaluation role, but instead define areas of union involvement. (39 references) (MLH)
