If someone is in crisis - expressing that they have overwhelming thoughts and/or feelings to either hurt themselves or hurt somebody else - encourage them to get urgent help. These webpages contain details of where to access urgent help if required.
The health, safety and wellbeing webpages provide guidance and information about Health and Safety, Occupational Health and wider employee health and wellbeing.
There is also Health and Safety Guidance for Managers which provides an overview of your Health and Safety responsibilities as a manager or supervisor.
