Sometimes your on-the-job injury might have been caused by the negligence of a third party. Depending on the circumstances, this other person or entity may be a designer or manufacturer of a defective piece of equipment or perhaps the driver of a delivery truck. If you are injured while at work due to the negligence of another party, you may have the right to bring a claim against that person or entity. These are known as “third party claims.” Typically, these claims are not filed in the workers’ compensation universe. Rather, they take the form of civil lawsuits and are filed in state or federal courts.
