Many people experience depression at some point during their working lives, but mental health issues are still stigmatised. As a result, those affected often don't disclose their problem or seek help for fear of repercussions, say the researchers.

To find out if the attitude of managers to mental health issues might be associated with workplace absenteeism rates and productivity, the researchers drew on an international audit (Global IDEA) of more than 16,000 employees and their managers in 15 countries with varying levels of income (GDP) and cultural norms.
