Spencer Johnson's "Who Moved My Cheese" is a lighthearted look at how we deal with change and can help people gain perspective on how they deal with parable the inevitablitiy of change.
And here is a video version of his parable that features a couple of mice, a couple of little people, a maze and, of course, cheese (as a metaphor for what we want and need).
It's simplistic approach is not for everyone, but this video can be used in a number of ways for yourself and in the workplace. I've even shown it to my kids to help them develop a healthy attitude towards change.
