Ask dumb questions. - Patrick Lencioni

Trust is the foundation of real teamwork.

Avoiding the issues that merit debate and disagreement not only makes the meeting boring, it guarantees that the issues won't be resolved. And this is a recipe for frustration. Ironically, that frustration often manifests itself later in the form of unproductive personal conflict, or politics.

Employees know that they ultimately pay the price when their manager doesn't get along with or cooperate with managers of other departments, leaving the staff to navigate the treacherous and bloody waters of organizational politics.
