Military and civil service carpenters, masons, and plumbers were surveyed using a job inventory checklist and relative time spent rating method along with background item responses. Job clustering and job typing of combined responses were performed and comparisons were made between civilian and military groups as well as comparisons between the two groups on several background variables. Data revealed that civilian and military members in the respective specialties are performing approximately equally. Significant differences were found between the two groups in the number of tasks performed, job difficulty, months in job, job interest, and job utilization of training and talents. Overall job interest and job utilization of training and talents were found to be relatively high for both civilian and military members. (Author/BM)
