NJ Workplace Violence: When Your Employer Fails to Protect You From a Dangerous Coworker or Customer

Reports of threats or violent behavior in the workplace rarely come out of nowhere. Most situations start with warning signs: repeated conflicts, aggressive language, or behavior that makes employees feel uneasy. At Brandon J. Broderick, we have seen how quickly these situations escalate when early signs are ignored or dismissed.

Employees complain about harassment or escalating confrontations, only to be told the situation is a “personality conflict” or a temporary dispute. But once conduct begins to affect safety, the situation changes. Employers are expected to take those concerns seriously, evaluate the risk, and act to protect their workforce.

When employees report safety concerns about a coworker or customer, New Jersey employers are expected to respond.

This article explains how the federal and state laws evaluate employer responsibility for workplace violence, who may be held liable, and when it’s time to consult a hostile work environment lawyer in New Jersey. 

Employer Duty to Protect Employees From Workplace Violence in New Jersey

Under the Occupational Safety and Health Act’s General Duty Clause, employers must provide a workplace free from recognized hazards that are causing or are likely to cause death or serious physical harm.

OSHA uses a broad definition of workplace violence. It covers acts or threats of physical violence, as well as harassment, intimidation, and other disruptive behavior at work. Most industries don’t fall under a single standard. 

But an employer’s duty starts before someone gets seriously injured. Threats, workplace stalking, intimidation, and repeated aggressive conduct all fall under the law. OSHA still issues citations when violence is a known hazard and employers fail to take steps to reduce the risk.

This becomes especially important when the danger comes from a coworker or repeat customer. Once management becomes aware of a threat, the focus turns to prevention. 

For example, while healthcare workers make up about 10% of the workforce, they account for 48% of all nonfatal violence injuries. New Jersey law requires covered healthcare facilities to establish a violence prevention program, form a committee, and provide annual training. It also requires recordkeeping to prevent repeat incidents. 

That statute doesn’t cover every workplace in the state, but it shows how seriously New Jersey treats predictable violence on the job. 

Employers are expected to react to:

• prior threats, intimidation, or aggressive outbursts
• repeated complaints to supervisors or HR
• a history of fights, stalking, or menacing behavior at work
• prior incidents involving the same customer, patient, or visitor
• jobs with known risks, such as healthcare, retail, late-night service, or direct public contact 

Once those facts are in place, it becomes a clear safety concern. If an employer ignores the risk or uses inconsistent discipline while allowing the same danger to continue, liability becomes much easier to prove.

When Employers Become Liable for Workplace Violence in New Jersey

Employer liability depends on what management knew about a potential safety risk. 

Notice doesn’t require formal documentation. When a supervisor observes a confrontation or sees escalating behavior, the employer is expected to recognize the risk. OSHA guidance reflects this approach. Awareness places employers on notice of potential misconduct.

How Repeated Coworker Threats Lead to Unsafe Workplace Conditions

Workplace violence rarely occurs without warning. Incidents follow earlier signs such as arguments, hostile comments, intimidation, or behavior that continues to escalate over time. 

Guidance from NIOSH reflects this pattern. Common warning signs include verbal expressions of anger, threatening behavior, signs of substance use, and the presence of a weapon. These are not isolated concerns.

These situations also place clear responsibilities on HR. When employees report a hostile or threatening environment, HR is expected to take those concerns seriously, document what is happening, and evaluate the risk. 

Liability often depends on what the employer knew or should have recognized. Reports of threats or ongoing conflicts contribute to the assessment. Treating it as a routine disagreement ignores the risk. In our experience at Brandon J. Broderick, when those concerns go unaddressed, they become powerful evidence in employer liability claims.

Timing also matters. Acting promptly supports the position that the employer responded appropriately, while delays can raise questions about whether the situation was handled with the necessary care.

What Inaction Looks Like in NJ Workplaces

Employers sometimes create liability through omission. Common failures include:

• ignoring complaints because no one had been hit yet
• refusing to investigate after reported threats
• keeping employees in close contact after a serious confrontation
• failing to involve security or law enforcement when a threat escalates
• doing nothing after a suspension, disciplinary event, or personal dispute that raises the temperature 

Workers’ compensation often covers physical injuries caused by a coworker assault on the job. In some situations, it applies to mental health injuries tied to workplace violence, such as anxiety or stress following a serious incident. 

Separate legal claims can focus on negligent supervision or failures to protect workers from foreseeable harm. These issues are not limited to coworker conduct. Repeated complaints about aggressive behavior or even racist customers show the same problem. Even when another individual is the direct cause of harm, the employer’s response leading up to the incident still matters.

A violent coworker affects the workplace. Employees may stop taking breaks alone, change shifts, or avoid certain areas altogether. If management knew about those changes and allowed the situation to continue, the focus shifts. The question becomes whether the employer allowed a dangerous condition to remain.

Workplace Violence by Customers and Third Parties: When New Jersey Employers Are Liable

OSHA highlights higher-risk environments such as healthcare and social service work, late-night retail, and positions that require regular interaction with the public. OSHA has also identified specific prevention measures. These risks are well documented.

Repeated Customer Threats Put Employers on Notice

An isolated argument with a customer doesn’t carry the same weight as repeated incidents involving the same individual. When threats or aggressive behavior continue over time, and employees report them, the situation becomes more predictable. It’s easier to identify as a safety issue. 

If management allows an aggressive patient or visitor to return without addressing the risk, the circumstances change. Allowing access without security changes affects how the situation is seen. In many cases we have built these repeated reports become an important part of how the risk is evaluated. 

What Reasonable Protection Looks Like

Employers are expected to respond to known risks. OSHA’s guidance points to practical measures such as engineering and administrative controls, training, and reporting systems. 

Protective steps include:

• Increased staffing levels
• A visible security presence
• Panic buttons or emergency alert systems
• Surveillance cameras
• Controlled or restricted access to certain areas
• Tracking individuals with a history of repeated incidents
• Clear procedures for removing people who pose a threat

Documentation also plays an important role. Records of incident reports and internal communications help show what management knew. When those records reflect repeated issues involving the same individual, they become a key part of the case.

How Workplace Violence In New Jersey Becomes a Hostile Work Environment

Unsafe workplace conditions and hostile work environment claims often overlap, but they are not the same. A workplace violence claim focuses on safety. A hostile work environment claim focuses on harassment connected to a protected characteristic. Under the New Jersey Law Against Discrimination (NJLAD), it includes race, religion, sex, national origin, disability, and similar categories.

New Jersey’s Division on Civil Rights explains that harassment based on these protected traits is unlawful when it becomes severe or persistent enough to affect working conditions. 

The federal Equal Employment Opportunity Commission looks at whether the conduct is severe or frequent enough to create an abusive work environment.

When threats or intimidation involve protected characteristics, it becomes a discrimination claim. For example:

• Threats accompanied by racial slurs
• Anti-religious or anti-Muslim remarks tied to intimidation
• Sex-based threats or harassment
• Mocking or targeting a worker’s disability

In some situations, one serious incident is enough, especially if it involves a direct threat.

Cases like this often involve more than one claim, such as unsafe workplace conditions, a hostile work environment, and negligent supervision. This overlap broadens both liability and the types of damages available.

Retaliation is also common. It can appear as:

• Discipline shortly after a complaint
• Schedule changes or loss of shifts
• Exclusion from work opportunities
• Negative write-ups
• Termination after reporting concerns

Workers who report harassment or unsafe conditions are protected by law. The U.S. Department of Labor also recognizes the right to report workplace hazards without punishment.

When a Dangerous Workplace Becomes the Employer’s Fault

Violence is rarely unpredictable. Liability comes down to awareness and response. 

Once the misconduct is reported, employers must act to protect their staff. Ignoring those risks or delaying action creates a record that is hard to defend. Workers dealing with aggressive coworkers or dangerous customers shouldn’t be left to manage it alone.
