Two distinct views of organizational commitment are examined in this study. Affective commitment describes an employee's emotional attachment to, identification with, and involvement in the organization. Continuance commitment is a behavioral view of commitment and describes an attachment to an organization based on "side-bets," or extraneous interests, such as pensions and seniority, which create costs in leaving an organization. These two dimensions are empirically examined for the case of 312 information systems (IS) employees. These findings demonstrate the importance of distinguishing between commitment based on a desire to stay in an organization and commitment based on a need to stay because of other factors, as well as the importance of fostering affective commitment in organizations.
