Does my work-related injury fall under workers’ compensation?

Injuries that qualify for worker’s compensation are sometimes due to the negligence of a third party. For example, if a scaffolding company negligently sets up scaffolding during construction of an office building and it collapses while a subcontractor is using it to install windows in the building, the injured worker has a worker’s compensation claim with his own employer and may also have a claim against that scaffolding company.
