Organizational communication is a fascinating subject that is constantly evolving. The second edition of this book was published in 2002 and I noted that organizations had changed substantially from the first edition. This edition reflects the significant changes since 2002 while retaining the in-depth discussions of critical organizational communication concepts. In addition, Dr. Mark Nelson has agreed to co-author this edition, making the coverage even more complete. We have added important insights concerning critical perspectives and the reader will note extensive updates, revisions, and current examples. The majority of the original chapter titles have remained, because they allow the reader to quickly access specific information. In every chapter, change, diversity, and the digital age are examined.
