A new report released by the U.S. Secret Service in partnership with the National Threat Assessment Center examined 50 mass attacks that occurred in workplaces across the United States between 2016 and 2023. The study provides a clear picture of who the attackers are, where the incidents happen, and what weapons are most often used.
Who the attackers tend to be
In every case reviewed, the assailant was a known individual – either a current or former employee, a regular customer or client, or a current or former romantic partner or relative. Most attackers experienced a significant stressor within five years of the incident, ranging from financial difficulties to conflicts at work. The overwhelming majority of the 50 attacks were carried out by a single male, with an average age of 41.
Where the attacks occur
Retail and service jobs were the most common settings, accounting for 28 percent of the incidents. Restaurants and bars followed closely, representing 20 percent of the cases. The remaining attacks took place in a variety of other workplace environments, including offices, healthcare facilities, and government buildings.
Weapons used
Firearms were the predominant weapon, employed in 43 of the 50 incidents examined. Knives and other bladed weapons were used in seven attacks, while four incidents involved other types of weapons or multiple weapons. In the Des Moines, Iowa, post‑office shooting on November 5, the assailant used a 9mm handgun.
Case example: Des Moines post‑office shooting
The November 5 shooting at the main branch of the Des Moines post office illustrates many of the report’s findings. Police identified the shooter, Jennifer Christine Pledger, as a postal service employee. While the motive remains unknown, the incident fits the pattern of a known individual using a handgun in a service‑oriented workplace.
Implications for employers and law‑enforcement
The report underscores the importance of vigilant security measures, employee assistance programs, and early identification of personal stressors that could lead to violence. Federal, state, and local law‑enforcement agencies are encouraged to work closely with businesses to develop threat‑assessment protocols and to ensure that warning signs are not ignored.
What the data means for communities
Understanding the common characteristics of workplace attackers helps communities prepare and respond more effectively. While the data shows that most incidents involve a single male shooter with a firearm, the variety of settings and motives highlights the need for comprehensive safety strategies that address both physical security and mental‑health support.
As the nation continues to prioritize the safety of workers, this report offers valuable guidance for policymakers, business leaders, and law‑enforcement officials seeking to protect American families and uphold the constitutional right to a safe workplace.
