It is a troubling fact of organizational life that executives with a track record of success, and who are expected to continue to succeed, are sometimes fired, demoted, or plateaued.

This publication reports on a study that extended CCL research by comparing contemporary derailed and successful executives in the U.S. and in Europe, and by comparing these results to the earlier findings.
