At some point, the positive effects of a CEO's continuing tenure (primarily in increasing task knowledge) are outweighed by the negative effects. Job mastery gives way to boredom; exhilaration to fatigue; strategizing to habituation. Outwardly, such executives may show few signs of this malaise because they may have been well socialized in the importance of keeping up executive impressions and appearances. However, inwardly the spark is dim; openness and responsiveness to stimuli are diminished. The continuing incumbency of these executives is dysfunctional for the organization.
