Should employers be held liable for injuries sustained during voluntary activities at mandatory company events?
The Illinois Appellate Court affirmed on October 13, 2026, that an employee injured during a voluntary costume contest at a mandatory work event is ineligible for workers' compensation. This ruling clarifies the distinction between mandatory job duties and optional social activities for Illinois employers.
Why it matters
The ruling provides a clear legal threshold for what constitutes compensable workplace activity during employer-sponsored events. For operators, this distinction limits liability when employees engage in voluntary recreational activities within a larger mandatory program.
The Illinois Appellate Court upheld the denial of a workers' compensation claim in case No. 3-26-0126WC. The commission and court found that the injury occurred during a voluntary recreational segment rather than a mandatory business meeting.
The players
Illinois Appellate Court
The intermediate appellate court in the Illinois state judicial system that reviews decisions made by administrative bodies like the Workers' Compensation Commission.
Illinois Workers' Compensation Commission
The state agency responsible for administering the Illinois Workers' Compensation Act and adjudicating disputes between employees and employers regarding workplace injuries.
The details
The dispute involved an employee who suffered a fractured ankle after falling from a bicycle while wearing a costume during a university event called BOOjay Buzz. While the overall event was mandatory for staff, the court determined that the costume contest was a distinct, voluntary activity. Because the employee chose to participate in the non-mandatory portion of the gathering, the court ruled the injury did not arise out of and in the course of employment.
Timeline
The injury occurred during the 2023 calendar year.
The Illinois Appellate Court issued its final ruling on October 13, 2026.
Market Landscape
This decision follows the precedent established in Mirretti v. Illinois Workers' Compensation Commission regarding the scope of compensable injury. It clarifies how state courts define the boundary between mandatory professional obligations and voluntary social participation.
Operators should clearly document which portions of employee events are mandatory and which are optional to manage liability exposure effectively. Consultation with legal counsel is recommended when structuring company gatherings to ensure distinct separation between job requirements and recreational activities.
The takeaway
The ruling underscores that mandatory attendance for one segment of an event does not extend workers' compensation protection to every concurrent activity. Management should explicitly communicate the optional nature of recreational side-events to employees in writing to avoid future disputes.
