Unionization efforts on community college campuses have increased fivefold over the past decade, this research addressed issues relating to increased levels of faculty unionization on community college campuses in Ohio. The purpose of this quantitative study was to examine and describe what, if any, relationships exist among faculty union membership and perceived leadership effectiveness of an institution. A review of literature identified a gap in the area specific to two-year institutions of higher education and unionization efforts of faculty at two-year campuses. Independent variables of academic division, age, gender, rank, tenure status, and education level were identified. Data was collected using a modified/blended Organizational Descriptive Questionnaire, and the researcher created survey instrument using a Likert-type scale. The results of this study provided descriptive evidence supporting the research hypothesis that a relationship does exist between faculty attitudes and leadership effectiveness toward unionization on Ohio two-year college campuses. A Cronbach's alpha analysis was conducted on the instrument with a value of 0.6883, which deemed the instrument valid and reliable. The data confirmed that the independent variables of academic division, gender, rank, tenure status, and education level have a significant impact on faculty member's decision to participate in union status, whereas age was shown to not have an impact on faculty members' union status. The results of the ODQ are based on Transactional and Transformational Culture Scores. A score above 0.50 is considered to possess positive culture, and a score below 0.50 is considered to possess negative culture. The ODQ findings showed that faculty had a more positive view of Transformational Culture Score 0.5563, with a more negative view of Transactional Culture Score 0.376. The results also indicated that transformational culture score correlated positively with effectiveness (r = 0.6791, p less than 0.055) and transactional culture score correlated negatively with effectiveness ( r = 0.503, p less than 0.005). Future research should be done on a national level to determine if the results are consistent with all faculty or if a geographic factor is present.
