Much of the responsibility for managing careers is shifting from employers to adaptive and proactive employees. A career management intervention based on action regulation theory trained 205 white collar employees to engage actively in their own career building by increasing their self-knowledge, career goal commitment, and career plan quality. As hypothesized, these three variables were positively related to subsequent career self-management behaviors, which led both directly and indirectly to career satisfaction almost 10 months after the intervention. Self-management career interventions based within an employing organization appear feasible.
