Workplace violence inflicts profound psychological and moral injury. Identity erosion, compounded by organizational denial, bystander inaction, and intersecting inequities, disrupts safety, belonging, and livelihood, complicating return-to-work decisions. This chapter synthesizes prevention, intervention, and postvention strategies for clinicians, emphasizing trauma-informed, culturally responsive, and ethically grounded care. It outlines comprehensive assessment, symptom measures, routine outcome monitoring, and evidence-based treatment pathways; centers therapeutic alliance and relational safety to address shame, self-blame, and moral injury; and integrates micro, meso, and macro systemic supports. Guidance is provided on legislative context, documentation ethics, and navigating compensation and reporting processes to improve access and outcomes. Advocacy is framed as helpful when it is client-centered, culturally attuned, and bounded by clear clinical roles while engaging systems to prevent disadvantage in care access. Clinicians are positioned as witnesses, allies, and change agents who name harm, believe clients, tailor care to context, and prepare for nonlinear recovery and reemployment fears. Integrating clinical excellence with measured advocacy can create change and advance psychological safety, equity, and accountability while sustaining hope and posttraumatic growth.
