Communication is no longer considered an optional soft" skill for climbing the corporate ladder. More and more businesses are placing emphasis on being able to communicate effectively. "Communicating Effectively For Dummies gives you the tools and insight you need to manage conflict, build teams and communicate persuasively at work."
This book is not very practically useful, as it is an expository text on the liberal arts, like a college textbook. People who are unable to build good relationships because they cannot communicate well with other human beings, either at work or in their daily lives, tend to blame others. In reality, however, it is due to the person's poor communication skills. A person who lacks communication skills cannot read books for a long time or think deeply about things. It's best to try changing the way you approach others.
A fairly basic book, it has great tips for those who are new to a management role and have to deal with a lot of different communication channels and styles. I recommend it to anyone as a quick review of communication best practices.
