Examined the effects of trust in administrative decision making, desire for decision-making power, satisfaction with the content of the work, and satisfaction with economic issues on pro-union voting in a representation election. 109 full-time faculty members from a 4-yr private college completed questionnaires. Regression analyses showed that distrust in administrative decision making and dissatisfaction with the work content contribute significantly to a pro-union vote. Demographic characteristics had no significant effects on union voting. Further analyses supported the hypothesis that pro-union voting was motivated by the desire of the faculty to improve its power position vis-à-vis the administration.(13 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
