Results from a major study of workplace wellbeing revealed half of respondents had experienced a mental health problem in their current job – but supportive managers made all the difference.

The study by mental health charity Mind surveyed more than 40,000 employees from 74 different organisations.

The study also showed that only half of those who had experienced poor mental health had talked to their employer about it.

Last year’s Thriving at Work report, an independent review commissioned by the Prime Minister, revealed that as many as 300,000 people lose their job each year due to a mental health problems, and that poor mental health at work costs the UK economy between £72 billion and £99 billion

Mind’s research also revealed that one in three employers do not know where to look for information and guidance.

Managers who felt their employer supported their mental health were far more likely to feel confident in promoting staff wellbeing.

And staff who felt their manager supported their mental health or could spot the signs that someone might be struggling were far more likely to say they would be able to talk about their mental health at work.

To help tackle the issue of mental illness in the workplace, Mind has created a new online portal called Mental Health at Work. It was launched on 11 September by HRH the Duke of Cambridge.

It is a free resource for employers and employees, with information, advice, resources and training to help improve wellbeing and give employees mental health support.

Paul Farmer, Chief Executive of Mind, said: “We are really proud to be involved in this piece of work, which offers a one-stop shop for anyone looking to improve mental wellbeing in their workplace and support staff with mental health problems.

“Even small changes to policy, approach and workplace culture can make a really big difference to the mental health of those around us.

“No matter the size of your workplace, and no matter where you work, Mental Health at Work can help you find what you need to start or continue your journey to better workplace wellbeing for everyone.”
