Practice 3　　Information and communications are central to modern society and organizations. One approach to understand the working environment is to consider an organization as a communications system. An organization that has open lines of communication with valid, honest information going up, down, and throughout the organization will be much more effective and a much better place to work than the organization that attempts to restrict the flow of information or distort and deceive. When leadership attempts to keep workers in the dark, workers tend to become distrustful. This undermines their cooperation.　　It is easy to understand the value and importance of open, honest communications and valid information. Yet, few organizations are able to function in this manner. In the long run, poor communication will undermine the entire organization. Restricting communication and distorting information are symptoms of short-range thinking. We must avoid these stupid, short-sighted traps and constantly strive for and open communications system with objective information.
