Find out if you have a violence prevention program in your workplace and what you should do -- if not, encourage your employer to develop one.
Violence prevention programs are required in many jurisdictions. A program is an ideal way to prevent workplace violence because it takes a very structured, well thought out approach to identifying hazards and reducing the risks for your organization and every worker.
If you are a worker, you can report your concerns to your supervisor, human resources department, or the person designated by your organization. You can also get advice from your employee assistance program (EAP) if you have one
