This study analyzes the impact of career plateau and job characteristics on people's attitudes or behaviors, but it also extends the traditional field of research on career plateau by taking into account the influence of factors linked to job characteristics on the relationship between career plateau and work-related attitudes. Our results show that subjective career plateau, job enrichment potential, role ambiguity and participation in decision making are related to various individual attitudes and behaviors. The impact of career plateau on these variables varies according to job enrichment potential, participation in decision making and role ambiguity. Although these direct and moderating effects are only significant for some of the facets of job satisfaction and behavior, it appears that these job characteristics can contribute to limit the negative consequences associated with career plateau.
