A new global study on employee engagement conducted by Right Management found the top five global engagement drivers to be:

1) I am committed to my organization’s core values
2) Our customers think highly of our products and services
3) My opinions count
4) I have a clear understanding of what is expected of me at work
5) I understand how I can contribute to meeting the needs of our customer

Notice that all five drivers reflect a state of mind - how employees feel (or how they perceive customers feel). Once again, emotion rules in the workplace.
