Which of the following can be considered a false claim in workers' compensation?

In workers' compensation, a false claim typically involves an attempt to receive benefits or compensation for an injury that has not legitimately occurred. Fabricating an injury is a clear example of a false claim because it involves deceit by the employee in order to gain financial benefits or coverage that they are not entitled to. This type of behavior undermines the integrity of the workers' compensation system and can have serious legal consequences for the individual involved.

The other options describe situations that generally fall within acceptable and legitimate bounds of workers' compensation. An employee injured at work is acting within their right to seek benefits. Seeking medical assistance after an accident is a standard procedure that is encouraged for the well-being of the employee. Reporting a workplace hazard is a critical aspect of maintaining a safe working environment and is also protected under various workplace safety laws. Therefore, the only choice that specifically represents a false claim is the fabrication of an injury.
