Workplace Violence

"Workplace violence is violence or the threat of violence against workers. It can occur at or outside the workplace and can range from threats and verbal abuse to physical assaults and homicide, one of the leading causes of job-related deaths. However it manifests itself, workplace violence is a growing concern for employers and employees nationwide." -OSHA Fact Sheet
There are 4 types of workplace violence:
Criminal Intent - The perpetrator has no legitimate relationship to the business or its employee, and is usually committing a crime in conjunction with the violence.
Customer/Client - The perpetrator has a legitimate relationship with the business and becomes violent while being served by the business.
Worker-on-Worker - The perpetrator is an employee or past employee of the business who attacks or threatens another employee(s) or past employee(s) in the workplace.
Personal Relationship - The perpetrator usually does not have a relationship with the business but has a personal relationship with the intended victim.
Workplace violence can start as small incidents involving negative remarks and inappropriate behavior. It may escalate to physical or psychological violence. Each situation is unique and professional judgment or outside assistance may be necessary to determine if intervention is necessary.
Take action and report your concerns to your supervisor, or human resources department. Alert Building Management of any concerns. Above all, take threats seriously.
Call 911 and report the incident. Notify Building Management and provide the same information given to 911. Evacuate the area, lock doors and stay out of view, put protection between you and the perpetrator.
