Workplace Prevention in Practice Pt.1: Shifting Workplace from Reaction to Care


Listen Later

In this first episode, Associate Professor Goodman Sibeko sits down with Associate Professor Nadine Harker to unpack what it really means for a workplace to take prevention seriously. Together, they explore how organisations can move beyond awareness campaigns to build genuine, prevention-oriented cultures.

Prof. Harker reflects on the shift from traditional workplace wellness models to a broader public health approach, one that views the workplace as part of a wider ecosystem and emphasises shared responsibility across leadership levels. She discusses how stigma continues to shape responses to mental health and substance use, and why visible, informed leadership is critical to changing that.

The discussion highlights how consistent policy, management engagement, and everyday practices can embed prevention into organisational life, making wellbeing a core part of how workplaces operate.
