Is unlimited length of service a healthy phenomenon?

This study examines the length of service among top managers in the Qatari banking sector. It investigates the longstanding argument that top managers tend to stay a longer period of time in their managerial positions. It also attempts to point out the related positive and negative consequences, and outlines the reasons why predecessors left their managerial positions. The study revealed that the ideal length of service is five years. It was indicated that there is an associative statistical relationship between length of service and managers' personal gains, regardless of the bank name. The results also showed the predecessors' reasons for leaving their positions.
