Research & Insights for Workplace Wellbeing

This systematic review explores why workplace health and wellbeing practices (WHWPs) often fail to improve psychological outcomes, focusing on implementation rather than intervention design. Across 74 studies, the authors identify that successful interventions depend on activating real workplace changes and sustaining them over time. Three critical success factors emerge: continuity of implementation, effective learning processes, and strong governance structures. Notably, improvements often occur through unintended social mechanisms such as enhanced relationships and culture. The findings highlight that organisational context, leadership, and adaptive implementation are central to achieving meaningful and lasting employee wellbeing improvements.

This research highlights that workplace wellbeing programmes often fail not because of what they are, but how they are delivered.

• Implementation quality is more important than the intervention itself
• One-off initiatives are unlikely to create meaningful or lasting change
• Sustained effort and continuity are critical for impact
• Learning and feedback loops help interventions adapt and improve over time
• Clear governance and ownership increase accountability and effectiveness
• Organisational context can enable or undermine success
• Improvements often come through changes in relationships and culture
