is a text designed as a guidebook, of sorts, rooted in theory, but which also advises on what to do and what to say when you encounter sources of workplace dysfunctionality. Through the creation of this text we sought to provide students with a comprehensive overview of traditional, as well as cutting edge, communication breakdowns (we invoke the term “toxic” to reflect the pervasive and corrosive effects these communication phenomenon have on professional interactions). In order to most effectively appeal to a college age audience, the voice of this text draws upon many relevant, and easily relatable examples workplace toxicity. While we build a foundation upon traditional communication academic sources, we also include a variety of social media and web related content. Instructors will appreciate the variety of online materials (activities, lecture notes, testing bank, etc.) which accompanies this book. Students will find its approach on modern workplace communication and relationships relatable, correct, and most importantly, applicable. This will be a textbook that will enjoy a space on their office bookshelf for years to come.
