Final answer:
The injured worker may have a claim for negligence against the driver of the van, depending on the specific circumstances and applicable laws. Comparative negligence may also be considered. The company and the driver could both potentially be held responsible for the accident.
Step-by-step explanation:
In this case, the injured worker may have a claim against the driver of the van for negligence. The driver has a duty to exercise reasonable care while operating the vehicle, and backing over another worker could be considered a breach of that duty. Whether the injured worker will be successful in their claim will depend on the specific circumstances of the accident and the applicable laws in the jurisdiction.
It is unlikely that the injured worker's own negligence in failing to watch out would completely bar their claim. In many jurisdictions, a concept known as comparative negligence may apply, which means that the injured worker's own negligence will be taken into account when determining damages.
Regarding the liability for the accident, it is possible that the company may also be held responsible if it can be shown that they were negligent in some way, such as failing to properly train the driver or maintain safe working conditions. However, the driver of the van may also be held personally responsible if their actions are found to be the primary cause of the accident.
