The purpose of this article is to examine halo effect and organizational commitment in relation to employees' job satisfaction and organizational supportive culture at universities in Taiwan. The study used a questionnaire to collect data from 210 female faculty members of Taiwanese universities. The conceptual model was tested mediating the effect of structural equation modeling with maximum likelihood estimation. This study not only found the mediating role of halo effect and organizational commitment between supportive culture and job satisfaction, but also proved that a supportive culture in universities is directly and positively related to job satisfaction and that emotional and identification‐oriented organizational commitment may affect job satisfaction in a positive way among female faculty members. © 2012 Wiley Periodicals, Inc.
