I don't advocate and neither does the book advocate becoming an intimidator because it makes you a lesser person, but one must know how to temporarily respond to toxic people as you begin steps to get that person mostly if not totally out of your life. I can tell you by experience that an abusive, yelling, belittling tyrant is often quieted by a visit from a process server or government employee investigating wrongdoing. If you work in healthcare, HIPAA is your friend: memorize it. If you look hard enough, you can find almost any manager committing HIPAA violations. Report that person to Health and Human Services. That makes you a whistleblower.
