This study examines gender differences in the career development of young white-collar workers during the first years of their career. In the descriptive analysis the hierarchical level of the first job and the job mobility of men and women are compared. Then, in the econometric part of the study, the probabilities to change jobs and to be promoted are estimated using panel probit models. The empirical dataset consists of a sample drawn from the white-collar worker data gathered by the Confederation of Finnish Industries (EK). The results of this study indicate that there are no significant gender differences in job mobility during the first years of the career. Women change jobs and are promoted at least as often as men. However, women are likely to start their careers from less demanding jobs than men. In addition, female jobs often turned out to be dead ends. When the share of women in the job increases both the probability to change jobs and to be promoted decreases.
