Our focus has been on the impact of instability on employment and new work practices in the aerospace industry. Specifically, we are examining three potential sources of instability -- changes in technology, changes in markets, and changes in organizations. To better understand this issue, we have conducted case studies in a mix of air frame, engine and avionics facilities -- spanning military and commercial sectors of the industry. We have also completed a national random sample facility survey, with data collected from 196 separate aerospace facilities. Over 400 individual workers, engineers, and managers have also completed individual surveys on the issues around employment and instability.
