What Is Workplace Violence?

Key Takeaways

✓Workplace violence includes any act or threat of physical violence, harassment, intimidation, or disruptive threatening behavior that occurs in a work setting, as defined by OSHA.
✓It ranges from verbal threats and emotional abuse on one end to physical assaults and homicide on the other. Most workplace violence doesn't involve weapons or fatalities.
✓The BLS recorded 761 workplace homicides and 57,610 nonfatal intentional injuries by another person at US worksites in 2021.
✓Workplace violence isn't limited to stranger-on-worker crime. Coworker conflicts, domestic violence that spills into the workplace, and customer aggression are all categories.
✓An estimated 73% of workplace violence incidents go unreported, making official statistics a significant undercount of the actual problem.

Workplace violence is broader than most people think. When HR professionals hear the term, they often picture an active shooter scenario. Those events are real and devastating, but they represent the extreme end of a much wider spectrum. The day-to-day reality of workplace violence includes a customer screaming threats at a retail worker, a coworker slamming a fist on a desk during an argument, an ex-partner showing up at someone's office, a patient striking a nurse, and a manager throwing objects in anger. All of these are workplace violence, and all of them affect employee safety, mental health, and productivity. OSHA defines workplace violence as any act or threat of physical violence, harassment, intimidation, or other threatening disruptive behavior that occurs at the work site. That's a deliberately broad definition because the harm caused by threats and intimidation is real even when nobody gets physically hurt. For HR teams, workplace violence isn't just a security problem. It's an employee relations problem, a legal liability problem, a retention problem, and, most fundamentally, a duty-of-care problem. Employers have a legal obligation under OSHA's General Duty Clause to provide a workplace free from recognized hazards, and workplace violence is a recognized hazard in every industry.

Four Types of Workplace Violence

OSHA and the National Institute for Occupational Safety and Health (NIOSH) classify workplace violence into four categories based on the perpetrator's relationship to the workplace.

Type	Perpetrator	Description	High-Risk Industries	Examples
Type 1: Criminal intent	No relationship to employer or employee	Violence committed during a criminal act (robbery, trespassing)	Retail, hospitality, taxi/ride-share, convenience stores, gas stations	Armed robbery of a late-night convenience store, carjacking of a delivery driver
Type 2: Customer/client	Customer, patient, student, inmate, or client	Violence directed at employees by people receiving services	Healthcare, social services, education, corrections, public transit	Patient assaulting a nurse, student threatening a teacher, inmate attacking a guard
Type 3: Worker-on-worker	Current or former employee	Violence between coworkers or from a former employee	All industries	Physical altercation between coworkers, terminated employee returning to threaten manager
Type 4: Personal relationship	Someone with a personal relationship to an employee	Domestic violence, stalking, or personal disputes that follow the victim to work	All industries	Abusive ex-partner appearing at the victim's workplace, stalker confronting employee in parking lot

Warning Signs of Workplace Violence

Most workplace violence incidents don't come out of nowhere. Research consistently shows that perpetrators typically display warning behaviors before an attack. Training your managers and employees to recognize these signs is one of the most effective prevention strategies.

Behavioral indicators

Watch for sudden and sustained changes in behavior: increased aggression or hostility, fascination with weapons or past acts of violence, direct or veiled threats ('People are going to regret this'), expressions of hopelessness or desperation, inability to handle criticism, blame-shifting and victim mentality, and social isolation from coworkers. No single indicator means someone will become violent. It's the pattern and escalation that matter.

Situational triggers

Certain workplace events can trigger violent behavior in someone who's already at risk: termination or layoff (especially if handled without dignity), disciplinary action or perceived unfair treatment, denied promotion or raise, workplace conflict that hasn't been resolved, personal crises (divorce, financial problems, substance abuse), and return of a disgruntled former employee. HR teams should have heightened awareness during these situations.

Escalation patterns

Workplace violence typically follows a progression. It starts with verbal aggression (yelling, cursing, hostile tone), moves to threats (direct or implied statements of intent to harm), then to intimidation (invasion of personal space, property destruction, following or stalking), and finally to physical assault. Intervening early in this escalation is far more effective than waiting until physical violence occurs.

Building a Workplace Violence Prevention Program

A prevention program doesn't need to be complicated, but it does need to be systematic and taken seriously by leadership.

Write a clear, zero-tolerance workplace violence policy that defines prohibited behaviors (threats, intimidation, physical aggression, weapons), applies to all employees regardless of level, and outlines consequences. Make sure employees sign an acknowledgment.
Establish a threat assessment team that includes HR, security, legal, and management. This team evaluates reported concerns and determines appropriate responses.
Train all employees to recognize warning signs and report concerns. Train managers specifically on how to respond to threats, de-escalate confrontations, and handle terminations safely.
Create multiple, confidential reporting channels. Some employees won't report to their manager, especially if the threat comes from their manager. Anonymous hotlines, HR direct lines, and online reporting forms all reduce barriers.
Conduct workplace security assessments: access controls, visitor management, lighting in parking areas, camera placement, panic buttons for high-risk positions (reception desks, late-night shifts).
Develop emergency response procedures for active threats. Include lockdown protocols, evacuation routes, communication plans, and designate rally points. Practice them.
Integrate workplace violence risk into your termination and disciplinary procedures. High-risk terminations should be planned with security present, conducted on-site (not remote if avoidable), and followed by immediate access revocation.

Legal Framework for Workplace Violence

There's no single US federal law that specifically addresses workplace violence, but multiple legal obligations create employer duties.

OSHA General Duty Clause

Section 5(a)(1) of the OSH Act requires employers to provide a workplace 'free from recognized hazards that are causing or are likely to cause death or serious physical harm.' OSHA has cited employers under this clause for failing to address workplace violence hazards, particularly in healthcare and late-night retail. While OSHA doesn't have a specific workplace violence standard, the General Duty Clause is its primary enforcement tool.

State-specific laws

Several states have enacted laws requiring workplace violence prevention programs. California's SB 553 (effective July 2024) mandates workplace violence prevention plans for nearly all employers. New York requires healthcare employers to implement programs under the Violence Prevention in Healthcare Facilities Act. Other states have similar sector-specific requirements. Check your state's requirements because this area is evolving quickly.

Employer liability

Employers can face civil liability for workplace violence under negligent hiring (hiring someone with a known history of violence), negligent retention (keeping an employee after learning they pose a risk), negligent supervision (failing to prevent foreseeable harm), and premises liability (failing to maintain safe conditions). If an employer knew or should have known about a risk and failed to act, courts have held them liable for resulting harm.

Responding to Workplace Violence Incidents

When an incident occurs, the response in the first minutes and hours determines both immediate safety outcomes and long-term organizational impact.

Immediate response

Ensure everyone's physical safety first. Call emergency services (911/999) if there's an active threat or serious injury. Secure the area and evacuate if necessary. Provide first aid. Don't confront an armed or actively violent person unless you're trained to do so. Account for all employees. Activate your emergency communication plan to notify employees of the situation.

Investigation and documentation

After the immediate threat is resolved, preserve the scene for law enforcement if applicable. Interview witnesses separately and promptly (memories degrade quickly). Document everything: what happened, when, who was involved, who was present, what was said, and what actions were taken. Notify your insurer and legal counsel. File regulatory reports as required (OSHA, local law enforcement, workers' compensation).

Aftermath and support

Don't underestimate the psychological impact on witnesses and the broader team. Offer Employee Assistance Program (EAP) counseling immediately and proactively. Some employees won't ask for help, so bring the resources to them. Hold a debrief (not in the first 24 hours, as immediate debriefing can be counterproductive) to allow the team to process what happened. Communicate transparently about what's being done to prevent recurrence.

High-Risk Industries for Workplace Violence

While workplace violence can happen anywhere, certain industries face significantly elevated risk due to the nature of their work, clientele, or operating conditions.

Industry	Primary Risk Type	Key Risk Factors	Incident Rate vs Average
Healthcare	Type 2 (patient/client)	Patient agitation, mental health crises, long wait times, understaffing	5x higher than private industry average
Retail	Type 1 (criminal) and Type 2 (customer)	Cash handling, late-night hours, working alone, public-facing role	Especially high for convenience stores and gas stations
Social services	Type 2 (client)	Home visits, working with high-risk populations, emotional client situations	Social workers face violence rates 12x the national average
Education	Type 2 (student) and Type 3 (worker)	Student behavioral issues, active shooter concerns, bullying among staff	21% of teachers report being threatened by a student (NCES)
Law enforcement/corrections	Type 2 (inmate/suspect)	Direct contact with violent individuals, high-stress confrontations	Assault rates among correctional officers are among the highest of any occupation
Transportation	Type 1 and Type 2	Working alone, cash handling, confrontational passengers, road rage	Taxi drivers face homicide rates significantly above average

Frequently Asked Questions

Is verbal abuse considered workplace violence?

Yes. OSHA's definition of workplace violence explicitly includes threats, verbal abuse, harassment, and intimidation, not just physical assault. Verbal abuse that creates fear, emotional distress, or a hostile environment is workplace violence and should be addressed through your prevention program. The fact that someone 'only' yelled threats doesn't make it less serious or less reportable.

Can an employer ban weapons in the workplace?

Generally, yes, but it's complicated by state 'guns-in-parking-lots' laws. Employers can typically prohibit weapons inside the workplace building. However, about 25 US states have laws that prevent employers from banning employees from keeping lawfully owned firearms in their locked vehicles in the company parking lot. Check your state's specific provisions because the rules vary significantly.

What should an employee do if they receive a threat from a coworker?

Report it immediately to their supervisor, HR, or through the company's reporting channel. Don't dismiss it as a joke or overreaction. If they feel in immediate danger, leave the area and call security or law enforcement. Document the threat: write down exactly what was said, when, where, and who witnessed it. Don't confront the person who made the threat directly.

Is workplace violence covered by workers' compensation?

In most cases, yes. Physical injuries from workplace violence are generally covered by workers' compensation if they arose out of and in the course of employment. Psychological injuries from workplace violence (PTSD, anxiety) are also covered in many jurisdictions, though the standards vary. Some states have specific provisions for first responders and healthcare workers who suffer psychological injury from workplace violence.

How should HR handle a domestic violence situation that affects the workplace?

Take it seriously and involve security. If an employee discloses that a domestic partner poses a threat, work with security to ensure the aggressor can't access the employee at work (flag photos with reception, restrict building access, relocate the employee's workstation if needed). Provide EAP referrals and domestic violence resources. Some states require employers to provide leave for domestic violence victims. The employee didn't cause this situation, and your job is to help keep them safe.

Does OSHA require a workplace violence prevention plan?

OSHA doesn't have a specific workplace violence prevention standard that applies to all employers. However, the General Duty Clause creates an obligation to address recognized hazards, which courts and OSHA have interpreted to include workplace violence when it's foreseeable. Additionally, specific states (California's SB 553, for example) now mandate written workplace violence prevention plans. Healthcare employers face the most specific regulatory requirements.
