As the focus on psychosocial risks, mental health and healthy workplaces continues to grow, so too do the many misconceptions. Taking an interdisciplinary, holistic approach from Safety Science, H&S Risk management and Neuroscience gives a much richer and deeper understanding to achieving robust mental health and compliance to regulatory requirements for Psychosocial Safety. This talk will demystify, clearly explain the differences, and the requirements for sustainable workplace mental health and healthy culture and explain what each requirement is and how it contributes to workplace mental health. We also discuss how doing them in a specific and right order is critical to obtaining sustainable mental health and why so many workplaces get it wrong.
