This study involved 108 administrative staff members in a private colleges that had been reorganized into universities of technology in Taiwan by February, 2004. In the study, we looked into the staff members’ perceptions of organizational change, job stress and organizational commitment, as well as the interrelationship among them. Major findings thorough further correlation analysis include: (1) organizational commitment has a positive correlation with the staff’s perceptions of organizational change, and a negative correlation with their recognition of the necessary sacrifice of the interests resulting from the reorganization. (2) the higher level the recognition of organization reform, the more job stress; and this job stress has significantly high negative correlation with organizational commitment, and (3) those administrative staff who are relatively young, unmarried, less experienced in working, and received fewer years of education tend to be better in recognizing organizational reform and job stress, but worse in organizational commitment. This finding shows that the recognition of organizational reform tends to negatively influence organizational commitment through job stress.
