Workplace Harassment and Workers’ Compensation: What Illinois Employers Need to Know About Psychological Injury Claims

Workplace harassment can damage morale, productivity, and retention – but does it also create workers’ compensation exposure? In Illinois, the answer is usually no, and understanding why can help employers manage risk and protect their organization.

Illinois Workers’ Compensation and Mental-Mental Claims

Under Illinois workers’ compensation law, psychological injuries are treated differently than physical injuries. The law distinguishes between:

• Mental trauma causing physical injury (e.g., stress-induced heart attack)
• Mental trauma causing mental injury (e.g., anxiety or depression without physical harm)

The second category—known as mental-mental claims—faces a much higher legal threshold. The Illinois Supreme Court’s decision in Pathfinder Co. v. Industrial Commission established that employees must prove a sudden, severe emotional shock, traceable to a specific time and place, which caused the psychological injury.  This means that ongoing harassment, even if deeply upsetting, rarely qualifies for workers’ compensation benefits.

 Why Harassment Usually Does Not Qualify

 Illinois courts have consistently ruled that anxiety, depression, or emotional stress developing gradually during employment is not compensable under workers’ compensation. The law applies an objective reasonable person standard, not a subjective one—so compensation cannot depend on an employee’s individual sensitivities.

For example:

• A bus driver who accidentally struck a pedestrian and suffered trauma was found eligible for benefits.
• An employee subjected to months of verbal abuse and racial slurs was not.

The difference? One involved a sudden, extraordinary event; the other involved ongoing stress.

Employer Action

Even though harassment claims rarely qualify for workers’ compensation, they can still lead to EEOC complaints, lawsuits, and reputational damage. Employers should:

• Implement a zero-tolerance harassment policy
• Train supervisors and employees on appropriate workplace behavior
• Provide clear reporting channels for complaints
• Document investigations and corrective actions
• Offer Employee Assistance Programs (EAPs) to support mental health

Key Takeaway

Illinois workers’ compensation law does not generally cover psychological injuries from harassment unless tied to a sudden, severe emotional shock. However, employers should not ignore harassment. Proactive prevention and swift response are essential—not just to avoid legal exposure, but to maintain a healthy, productive workplace.
