Clear language does not oversimplify, or leave out essential information, or bore the reader. Clear language is writing that is widely accessible, because it is as direct as possible, and because it begins with people's experience. Clear language does not patronize people. It includes them.
Clear language allows you to reach a larger audience with your message. And that's important to unions - in campaigns, bargaining, health and safety, in all kinds of union communications.
Clear language is an approach to communication that begins with the needs of your readers, a specific audience. When we speak directly to someone, we get immediate feedback. We can adjust our message if the audience does not clearly understand.
Written communication poses a greater challenge. We can't get immediate feedback. We have to think in advance about the needs of our readers and our needs. We have to seek feedback so that our message is as clear as possible.
