The recent workers' compensation claim case of City of Brighton v. Rodriguez illustrates how unexplained work injuries could still be compensable, so long as the injury arises out of employment.
Our Atlanta workers' compensation attorneys know the key point in these situations is that the "arising out of" requirement. This refers to the causal origin of the injury, but it doesn't necessarily mean that the injury was caused by employment. This requirement is met when, by reason of the employment, the worker is present at a location where he is injured either by a third person, an outside force or conditions of the location.
This is an important point because not all compensable work injuries stem from actual work duties.
