Spot the Signs: Preempting Workplace Violence Through Intelligence

Written by: Nick Freeman

It was a regular Tuesday morning.

The HR director of a mid-sized manufacturing firm was scanning her inbox when an urgent email arrived. A line supervisor reported that one of the team leads—normally dependable and calm—had been snapping at coworkers, isolating himself, and making dark jokes about “finally having enough.” A few days earlier, he had been seen pacing in the parking lot, visibly upset after a tense meeting with management.

Any one of these behaviors might not raise alarms. Together, they signaled that something was wrong—and that the organization might be one heated moment away from a serious workplace incident.

For companies in manufacturing, healthcare, logistics, and corporate offices, this scenario is all too real. Workplace violence rarely erupts without warning. There are almost always pre-threat behavioral indicators, and leaders who recognize them can intervene before a crisis occurs.

Why Hidden Threats Keep HR and Legal Leaders Awake at Night

For Human Resources directors, General Counsel, COOs, and risk leaders, the workplace is a balancing act. You must:

• Protect employees from harm
• Stay compliant with workplace safety and employment laws
• Maintain business continuity and protect the company’s reputation

The problem is that the first signs of danger are often subtle:

• A reliable employee suddenly becomes irritable or withdrawn
• Minor conflicts start escalating in tone
• Anonymous complaints mention intimidating or threatening behavior
• Personal crises—divorce, financial stress, or legal trouble—begin to spill into the workplace

Internal investigations often reveal that multiple employees noticed these signals weeks or months before an incident. But without a process to connect the dots, the organization remains exposed.

According to the Occupational Safety and Health Administration (OSHA), nearly 2 million U.S. workers report being victims of workplace violence each year, and many more near misses go unreported. The costs range from potential lawsuits to devastating human consequences.

The Critical Role of Pre-Threat Behavioral Indicators

Workplace violence almost always follows a discernible escalation pattern. Recognizing that pattern early is critical.

Common indicators include:

• Escalating verbal aggression—raised voices, personal insults, or hostile emails
• Social withdrawal—sudden isolation from coworkers or team activities
• Fixation on grievances—persistent anger over perceived unfair treatment or discipline
• Visible personal stressors—family, financial, or legal problems affecting behavior
• Physical cues—pacing, clenched fists, or erratic body language
• Comments about violence or weapons, sometimes shared casually or online

It is rarely a single event that signals danger. Instead, risk becomes clear when these indicators accumulate over time.

Case in Point: The Missed Signals of a Near-Tragedy

Consider a logistics company in the Midwest. One of their warehouse supervisors was going through a bitter divorce. Over a few months, coworkers noticed:

• He stopped joining team lunches
• He overreacted to small mistakes
• He spent long periods alone in his car during breaks

No formal report was filed. HR only became aware after a night shift supervisor found him in the parking lot, visibly distressed and gripping a baseball bat while talking about “getting even.”

Fortunately, security intervened before the situation turned violent. Later, an internal investigation revealed that five different employees had observed warning signs for weeks. None of them knew how to escalate their concerns. This scenario is more common than most leaders realize. The signals were there. The process to act on them was not.

From Observation to Action: Building a Prevention Framework

Preventing workplace violence requires more than a handbook and an annual training session. A proactive strategy includes:

1. Creating an Early-Warning Culture

Employees need to feel safe raising concerns without fear of retaliation. Encourage managers to document and report changes in behavior so small pieces of information can be connected.

2. Acting Quickly on Reports

When a report comes in, investigate promptly and document findings. A single complaint may seem minor, but combined with other observations, it can reveal serious risk.

3. Leveraging Protective Intelligence

Chesley Brown’s Protective Intelligence solutions collect and analyze behavioral data across HR, security, and legal teams. By identifying patterns instead of isolated incidents, leaders can take action before threats escalate.

4. Aligning HR and Legal

HR and General Counsel should work in tandem. Coordinated action protects both employees and the organization by keeping investigations compliant while reducing liability.

5. Implementing Strategic Prevention Measures

Once patterns emerge, leaders may:

• Offer Employee Assistance Programs (EAPs) or professional counseling
• Adjust duties or workplace settings temporarily
• Increase on-site security or monitoring in sensitive areas
• Engage Fractional CSO or security consulting services to develop a long-term prevention plan

Why Mid-Sized Companies Are at the Greatest Risk

Large corporations often have dedicated security and intelligence teams. Small companies can spot changes quickly because everyone knows each other.

Mid-sized companies sit in the most vulnerable position:

• Big enough that warning signs get lost across departments
• Small enough that a single incident can disrupt operations or destroy morale
• Often without a full-time security executive or intelligence function

This gap is why many mid-market companies partner with Chesley Brown for Fractional CSO services and Protective Intelligence programs. These services help organizations identify, track, and act on risk signals before they escalate.

The Takeaway: Prevention Beats Reaction Every Time

Workplace violence is a risk that organizations cannot afford to overlook. Early recognition of pre-threat indicators, prompt internal investigations, and proactive intelligence programs can prevent tragedy and protect both people and the business.

Leaders who act on subtle signals avoid the nightmare of learning the hard way. Those who wait until the news trucks arrive are already too late.
