But 95% of employees cited a reason other than workplace stress for their absence because of the stigma attached to mental health.

The charity, Business in the Community, is running the largest ever survey of mental health at work and Prospect is encouraging all members to take part.

The survey aims to raise public and employer awareness of the importance of mental wellbeing, including the crucial role of the line manager.

Questions focus on levels of employee mental wellbeing, awareness of mental wellbeing issues and managers’ ability to support mental wellbeing.

The charity wants to help:

• end the stigma associated with mental wellbeing
• identify factors that help or hinder the mental wellbeing of UK employees
• understand how employers are responding to mental health issues and
• identify how equipped employees and line managers are to spot the early warning signs of poor mental health.

Business in the Community lobbies for work mental health improvements. The survey is endorsed by the TUC and supported by Mind, the Chartered Institute of Personnel and Development, the Work Foundation, Maudsley, Learning at Work and Mental Health First Aid England.

Help end the silence and take the survey

Participants must be in employment in the UK. The findings will be published in time for World Mental Health Day on 10 October.

The closing date is 29 July.
