In some cases, both a civil lawsuit and a Workers’ Compensation claim may be filed against the employer. If a third party or defective product caused the injury then a personal injury lawsuit may be available as well. For example, when an employer asks an employee to drive on a work-related errand, and a car accident occurs in the course of that errand, the worker may file a workers’ compensation claim against his employer, as well as a “third party” lawsuit against the other driver.
