Workplace injuries are those injuries that arise out of and in the course of gainful employment. Generally, injuries received while not at work are not covered. However, if workers sustain injuries during an event or occasion that was sponsored by the company they are working, such injuries will be covered generally. Excluded are work injuries to private household workers and home injuries.
Workplace injuries also include illnesses occurred as a result of the environment in which an employee works. An example is black lung disease, which is seen in coal miners, or carpal tunnel syndrome, which is seen in office workers.
