No matter how small an injury, a worker must "forthwith report" the accident and the resulting injury to the employer, according to Arizona Workers' Compensation laws. (Ariz. Rev. Stat. §23-908 (E)). The injured worker must report the injury when it occurs or as soon as she becomes aware of her condition. Failing to timely report a work-related injury could jeopardize the claim for workers' compensation benefits and can lead to a difficult battle over whether the injury happened on the job.
