Jail staff who harbor negative attitudes toward their jobs can be detrimental for the functional operation of the organization. Presumably, personnel who are more involved with their work should have lower levels of stress and higher levels of job satisfaction and organizational commitment, compared with those who are not involved. The current study examined the effects of job involvement on job stress, job satisfaction, and organizational commitment at a large county jail system in Florida. Based on multivariate analyses of staff survey data, the results revealed that job involvement was negatively related to job stress and positively related to both job satisfaction and organizational commitment. The implications of these findings for correctional research and practice are also considered. Abstract published by arrangement with Sage Journals.
