The purpose of this paper is to explore obstructional factors of the female promotion reflected in employees' descriptions about their preference for male or female managers. We used an analytic framework by Ragins and Sundstrom (1989), based on four levels of analysis : societal, organizational, interpersonal, and individual. Seven hundred and eighty-five employees (467 males and 318 females) in several industrial organizations answered the question which asked them whether they wanted to have a male or a female supervisor, and described the reasons by open ended question. A little over fifty percent of male subjects and about thirty percent of the females prefered male supervisors. The following results were obtained from content analysis about the reasons of the male preference : 1) The reasons were classified under 23 categories belonged in either four levels. 2) Subjects in managerial position prefered a male manager from mainly reasons belonged in societal (eg. 'Because many women have the responsibility for their family'), organizational (eg. 'In our company, all managers were males'), or individual level (eg. 'Women don't have the ability to be a leader'), while the other subjects mainly refered to interpersonal (eg. 'It is difficult to communicate with a female superviser') or individual levels'. 3) Subjects' sex or their attitude toward sex roles didn't associate with the kind of reasons of male preference. The direction of further study was discussed.
