A model of job socialization based on the joint effect of decision latitude and psychological demands are developed to predict how behaviors learned on the job would carry over to leisure and political activities out-side of work. The model is tested with a longitudinal national random sample of the Swedish male work force (1:1,000) in 1968 and 1974 (nlongitudinal = 1,508), including both expert and self-reports job data and 92% (1968) and 85% (1968-1974) response rates. Workers with more "active" jobs (high decision latitude and high demands) become more "active" in their political and leisure activity from 1968 to 1974 (p < .001). Cross-sectional analyses and work experience cohort results (1968) are consistent. Associations are unaffected by control for education and father's education, limiting an alternative explanation via personal background. The content of work may substantially affect political behavior, culture, and the economic equilibrium of service-oriented societies.
