As a first contribution to this field of questions a special survey on workplace and employment change was conducted in September 1970 (Mikrozensus MZ7003). It produced - for the first time in Austria - important results on the frequency of job change and on the stability of employments. In this study, another problem is of interest, namely the course of the career, on which there exists no statistic information. This time we don’t ask how often an employee has changed his job up to the time of the interview. The focus is now on all stages of his or her career.
