Losing work is a key driver of poor mental health, and 'good' work plays an important role in promoting health and wellbeing. There is an emerging evidence base on what works in employment support for those with mental health problems — particularly around effective job search support, peer support and alignment of employment services and health. Effective workplace interventions, particularly those focused on leadership and line management, job design and working arrangements, can also make a difference. We now need to build on this evidence base, test and learn from new approaches, and encourage future investment in, and alignment of, new approaches both in public services and by employers.
