This guide ties mental health and well-being directly to DEI outcomes, centering psychological safety and belonging as the core enablement levers. It outlines the 7 pillars of well-being (physical, career, financial, social, community, emotional, purpose-driven) and shows how underrepresented groups experience distinct headwinds—requiring targeted supports (licensed experts, manager upskilling, mindful talent practices, storytelling, and well-being-focused ERGs). It defines psychological safety (four stages: inclusion, learner, contributor, challenger) and the three operating zones (learning, anxiety, comfort), then makes the business case: higher engagement, creativity, performance, and retention.
