What do you do when you have something you do not understand at work?
What do you do when you need advice, instruction or direction at work?
In most situation, you would look toward your superior for an answer or solution.
What if one day your supervisor come to you and ask, "What should we do?"
Most of us expect our superior to have more experience/knowledge than us, know more than us and have all the answers to our questions at their finger tip. No one could imagine having a supervisor who does not has answers to problems, much less accept a supervisor who knows less than him or her. You'll question the supervisor's ability in leading you and how did he or she get into that position.
But isn't having a supervisor who is willing to be truthful about what he or she does not know better than someone who pretends to know.
Would you rather be lead by someone who does not know and pretends to know?
