Rising frequency of violent workplace encounters
OSHA recorded 20 severe cases of stabbing, cutting, or slashing by other persons in the most recent reporting period. These incidents most frequently result in cuts, lacerations, and punctures, though one in four cases involves life-threatening injuries to internal organs and major blood vessels.
The physical toll of these events is significant, with 60% of all reported injuries occurring in the abdomen. These attacks often lead to long-term complications, requiring emergency surgery and extensive recovery periods for the affected workers.
The data shows a clear upward trajectory, with incidents rising from 12 in 2024 to 14 in 2025. This trend is driven largely by interactions with co-workers and work associates, who account for 35% of all identified sources of injury.
Retail trade and accommodation and food services are the primary settings for these violent events, together accounting for 55% of all reported cases. These high-traffic environments often lack the necessary security protocols to protect employees from both external assailants and internal conflicts.
Top causes based on OSHA incident reports
Workplace violence involving sharp objects typically stems from three primary sources: co-workers, criminal assailants, and customers. These incidents often occur during verbal disputes that escalate rapidly, or through unprovoked attacks in parking lots and service areas. Whether it is a pocket knife used during a shift or a weapon brought by an outsider, the mechanism of injury is almost always a direct, intentional act of violence against an employee.
| Injury Type | Incidents | |
|---|---|---|
| 1 | Cuts, lacerations, punctures without injury to internal structures | 15 |
| 2 | Injuries to internal organs and major blood vessels | 5 |
Employers are legally obligated under the OSHA General Duty Clause, 29 CFR 5(a)(1), to protect workers from recognized hazards, including workplace violence. When an employer fails to implement adequate security measures, such as restricted access, surveillance, or conflict de-escalation training, they may be in violation of their duty to maintain a safe environment.
Where these injuries occur most frequently
Retail trade leads all sectors with 35% of these incidents, followed by accommodation and food services at 20%. These industries rely on frequent public interaction and high-pressure service environments, which can create volatile conditions if proper security and staffing levels are not maintained.
In these high-risk sectors, employers must adhere to OSHA guidelines regarding workplace violence prevention. This includes conducting thorough risk assessments, implementing physical security controls, and providing comprehensive training on how to identify and report threatening behavior before it escalates to physical harm.
From actual OSHA investigation files
The documented incident reports reveal a pattern of sudden, violent escalation in the workplace.
