Effects of supervisor gender on promotability of female managers

In order to more fully understand the importance of same-gender competition in female supervisor-subordinate working relationships, this study examined the effects of supervisor gender on promotion probabilities for Korean female managers with or without managerial qualifications (e.g. mentoring participation and job ranks). Using a balanced panel sample of 568 Korean female managers in each of four waves (in total, 2272 female managers over 7 years), we conducted a multinomial logistic regression analysis to estimate the promotability of female managers. Our findings showed that mentoring participation negatively affects promotion probability for female managers when they have female supervisors (vs male supervisors). Competitive interdependence can be exacerbated between female managers and female supervisors, especially when they are qualified to compete for the same resources and opportunities, which are limited for female managers and supervisors.
