This is a study of differences between women and men in their responsiveness to formal organizational career management. Questionnaire data from 272 men and 101 women were analyzed. It was found that women's individual career variables were mostly similar to men's, but their responsiveness to organizational career management was higher than men's. Women's career effectiveness (performance, attitudes, identity, and adaptability) and career planning increased when the level of perceived organizational career management was high. The sex difference remained even when the effects of two other responsiveness‐reducing factors, managerial position and tenure, were controlled. The results are interpreted in terms of women's cognitive construction of organizational reality. It is suggested that human resource managers have to distinguish between two different objectives: enhancing women's effectiveness vs. enhancing their career progress. To attain the first objective, formal career management systems should be developed. To attain the second, it is argued that women need to relate differently to the informal organizational system.
