I often wonder what really motivates people.  I had the opportunity to watch Daniel Pink present this year and I agree with all of his science on motivation.  However, I know there is more to motivating employees and keeping someone engaged in the workforce.  Research tells us that 50% of people leave their bosses, not their jobs.  There is strength in that research and I have seen it played out over and over again.  So, should we do as Daniel Pink states and provide autonomy, purpose and personal mastery or should we just make sure bosses are well trained to motivate employees in a way that keeps them engaged and not looking fro a new job?
