Library staff are expected to provide exceptional service while navigating behavior that can be demanding, inappropriate, or emotionally charged. This interactive session introduces a trauma-informed approach to asserting compassionate boundaries, helping participants stay kind, clear, and courageous under pressure. Rooted in neuroscience and informed by real-world library scenarios, participants will explore how nervous system activation influences communication, why boundary testing occurs, and how to respond with grounded clarity rather than reactivity. This session empowers librarians to recognize early warning signs, and learn practical strategies for responding in ways that protect staff well-being while maintaining welcoming, inclusive spaces.
