An injury or illness is considered work-related if the condition Arose Out of Employment during the Course Of Employment (AOE/COE), due to an event or exposure at the workplace.  A condition is not work related if it arose coincidentally while at the work place, but due to factors outside the workplace, or while performing personal or volunteer activities at the workplace.  Thus the condition must be caused or significantly aggravated by an identifiable event or exposure arising from work.
