Business Communication: Managing Information and Relationships 

In many ways, the history of human civilization chronicles the increasing centrality of communication. Communication establishes relationships and makes human organization and cooperation possible. Whether you recognize it or not, you have no choice but to communicate. If you try to avoid communicating by not replying to messages, you are nevertheless sending a message, but it may not be the one you want or intend. When you don’t say yes, you may be saying no by default—and vice versa. The only choice you can make about communication is whether you are going to attempt to communicate effectively.
