You've probably seen this:
A top executive stands before a meeting of employees and announces that he or she wants them to speak up if they see anything that can be improved in the organization.
Suddenly, throughout the audience, there are these side glances. Some people look at the floor. Others discover an intense interest in their schedule books. Those in the back may even bolt for another cup of coffee.
And the unspoken question is, "Do you really mean that?"
Another question is, "Even if you mean it, what about those other folks up on the podium?"
