The usual concept is that someone else’s fault in a fatal incident is grounds for a wrongful death case. The exception to this is when your loved one died as the result of a work-related accident. The concept of negligence does not apply in workers’ compensation claims. You cannot sue an employer for wrongful death in almost all cases.There are very few exceptions to that doctrine in Arizona. This means that your compensation for a loved one’s death on the job will likely be lower because you do not qualify for the full lost wages or pain and suffering damages in a workers’ compensation claim. However, you also do not need to prove that anyone was responsible for your family member’s death. This is even true if your loved one made a mistake on the job that caused the accident.You can file a wrongful death case if a third party caused a fatal work accident. For example, if your loved one died due to defective work equipment, you can sue the manufacturer in a product liability case. If a third-party contractor or subcontractor caused the death at a construction site, you can file a wrongful death claim against them.
