This dissertation examines the effect that the introduction of an advanced manufacturing technology, specifically robotics, has on the work force of an aerospace defense company. In this endeavor, there are two main objectives. First, this study determines whether workers feel that their jobs are threatened by the introduction of robotic technology. Secondly, the research compares the degree to which workers from different labor types feel this threat. A review of the literature reveals that the technical factors involving manufacturing technology have been thoroughly examined and discussed, but the effect that they have on the work force has been somewhat neglected. This dissertation develops ten hypotheses to ascertain the perceived threat to job security for workers within an aerospace defense company. This study is based on an employee survey that examined the employee's perceived threat to job security by the introduction of robotics. The primary research was obtained from employees within an aerospace defense company through the use of questionnaires in a three phase approach. The first phase utilized a pretest that sampled the questionnaire prior to the company-wide solicitation. The second phase administered the questionnaire to the three labor types within the work force. Phase three consisted of data reduction …
