Many organizations today are concerned with career plateau. Most researchers in this field have chosen either an historical approach based on objective measures, or a psychological approach based on people's perception of being blocked in their career progression. Ettington (1992) shows the interest of analyzing career plateau by using both approaches jointly. This study aims at validating some of her results on samples of Quebecian and French managers and to study the impact of career plateau on various aspects of job stress. Results confirm most of Ettington's results: the feeling of being plateaued has a different impact on satisfaction and stress when managers are objectively plateaued or when they are not. The study also shows the mediating effect of locus of control and discusses possible implications for research and for companies.
