Fortune.com is offering readers of its web site the opportunity to ask Fred Smith questions.
http://money.cnn.com/magazines/fortune/questionsfor/index.html
The only word of caution is to briefly introduce yourself - something like "I am a FedEx worker for XX years" - so that your question is grounded in your first hand experience and knowledge of the company; that way your question can't be dismissed out of hand.
Go ahead. Fire away.
