When an injured worker has a valid work injury it is compensable. The California compensability statute is Labor Code Section 3600. In order for an injury to be compensable, it must arise out of and occur during the course of employment. This rule is commonly referred to as AOE/COE. To determine if something arises out of the employment we look to the origin of the risk. Did the risk grow out of work-related activity, was it a mixed cause or was it purely personal? If the origin of the injury was purely personal then it may not be work related. However, even personal comforts like going to use the restroom are considered to be work related because they are incidental to the employment.
