Listen to Win is a foundational book for your library. It offers a wealth of detailed information that will take a lifetime to apply. It is not a workbook, but it provides material that is transferable into the workplace on a day-by-day, hour-by-hour basis. It is very useful as a tool to improve your own listening skills and those of your subordinates. Currently it is out of print and not easy to find, but it is well worth the effort.
