What is best practice for employers dealing with mental health problems at work? The World Health Organisation estimates that depression and anxiety cost the global economy about one trillion dollars a year in lost productivity. About half of all workers suffer from poor mental health but few of us talk to our employers about it. So how can an employer support someone going through a crisis, and does the workplace have a role in breaking down the stigma around mental health? Manuela Saragosa tries to answer some of these questions with guests, Professor Sally Maitlis of Saïd Business School, University of Oxford; Mary Daniels entrepreneur, author and coach; and Nicky Young, managing director at MullenLowe salt.
