Yeah, the book is really good. But also only useful in really exceptional situations. (Speaking about workplaces, only in a toxic workplace there is use for it.)
Check out Crucial Conversations (https://www.amazon.com/Crucial-Conversations-Talking-Stakes-...). It's a framework that I've found immensely helpful.
