Leadership and managing people is something that you really need to work at and consciously look for ways to improve. For any new managers, as well as seasoned managers, I recommend reading the following books by Patrick Lencioni in their entirety:

• The Five Dysfunctions of a Team
• The Three Signs of a Miserable Job
• The Four Obsessions of an Extraordinary Executive
• Silos, Politics, and Turf Wars
• Death by Meeting
• The Five Temptations of a CEO

Patrick Lencioni is, in my opinion, the leadership guru of the 21st century. Check out Amazon.com for these books.
