Weitz (1952) argued that job dissatisfaction would be more predictive of turnover if it was considered in light of an individual's predisposition to be satisfied with everyday life events. In the present study it was hypothesized that affective disposition moderates the relationship between job satisfaction and voluntary turnover. Using data collected from a sample of nurses, support was indicated for the hypothesis. Individuals dissatisfied with their jobs but positively disposed to their life in general were the most likely individuals to quit. Furthermore, the relationship between job dissatisfaction and turnover was moderately strong for those with "positive" dispositions but negligible for those with "negative" dispositions.
