Your materials are ready. Your technology has been tested. No matter how prepared you may feel, there can always be a participant who challenges you in unexpected ways. Learn about a variety of difficult behaviors and how to welcome a participant's energy without indulging it. You will walk away with a three-step model that helps in identifying challenging behaviors, shifting participant energy, and creating a self-developed reaction strategy. This session was recorded at the ATD 2019 International Conference & EXPO, May 19 - 22, 2019 in Washington D.C.
