In all states but Texas an employer must have workers compensation insurance when there are more than a certain number of employees, varying from three to five, depending on the state. Workers comp insurance, as this coverage is generally called, pays for medical care and replaces a portion of lost wages for an employee who is injured in the course of employment, regardless of who was at fault for the injury. When a worker dies as a result of injuries sustained while working, the insurance provides compensation to the employee’s family.
