Every organisation is different, and will require a unique set of policies to best deal with the needs of its staff. It’s therefore important to identify what these needs are, and how a workplace mental health programme could begin to address these.
The European Network for Workplace Health Promotion (ENWHP) has produced a questionnaire whose questions will help you focus on key workplace issues. A copy of the ENWHP survey is available here if you would like to make use it for your own organisation.
If you need further help you can find out more from the ENWHP website.
