This special issue of "Per Linguam" is entirely devoted to a study of language training in industry in the Cape Town metropolitan area of South Africa that examined the need for language instruction from both the management's and workers' points of view. Data were obtained from a literature review, a mail survey, and individual interviews. The final report includes an introduction and overview of the situation, a survey of the literature on the effects of language training on labor relations and productivity, the findings of an opinion survey of personnel managers, a report of survey interviews held with personnel managers, a report of survey interviews with black unskilled and semi-skilled workers in the area, and a summary of findings and recommendations. The findings concern: (1) the need for industrial language training and its effectiveness; (2) foreman/supervisor communication problems; (3) black workers' communication problems; (4) the contribution of language instruction to black worker promotion and elimination of communication problems; and (5) the correlation of management's and workers' opinions. Recommendations concern: (1) the need for language teaching; (2) improvement of instruction; (3) language course criteria; (4) language training as an integral part of an overall training program; (5) government recognition of and aid for language training; and (6) the role of postsecondary institutions. Further research needs are discussed. (MSE)
