So far, mine is "Improve Your Job By Improving Your Relationship With Your Boss". http://hub.me/ag8Ef
It contains information that I've learned over the 35 years that I've been working, both as an employee and as a manager.
I like it because I think the information in it can make a difference to both employees and managers. It can improve self-satisfaction and compensation for employees and make the manager's job easier. That makes things a little bit better for everyone involved.
