Keuring van leiers onder Bantoemynwerkers
Failure to meet die operational ratios for supervisory labour on the mines encouraged the employment in supervisory categories of labour rejected by the selection programme. This reduced the effectiveness of the Leaderless Group Tests as selection instruments. Overhaul of the selection programme entailed the study of boss boy requirements and the development of scoring procedures designed to meet these needs. In order to eliminate the effect of feedback and test sophistication on scoring procedures, this overhaul of the selection programme included the development of new test situations. The working hypotheses that, to be successful, the boss boy had to be acceptable to both superiors and workers was accepted initially and two questionnaires prepared to test this hypotheses among superiors and subordinates. The one questionnaire was completed by mine overseers, shift bosses, developers, stopers and general miners and the second questionnaire was administered to Bantu workers with underground experience but no previous boss boy experience.
