Employees who work for many businesses are covered by worker compensation insurance. This coverage provides benefits in the event of an injury that occurs at the place of work or while performing the duties of one’s job. However, some people have abused this benefit program by faking sickness or injury in hopes of receiving benefits. For this reason, many lawyers practice in the field of worker compensation insurance, both defending employee claims and arguing against those claims. Often, the cases come down to which side has the most-believed expert witness who can testify about the illness or injury.
