Eligibility for workers' compensation benefits generally extends to most employees who suffer injuries or illnesses in the course of their employment. This includes full-time, part-time, and temporary workers. However, eligibility criteria can vary by state and occupation. Independent contractors, volunteers, and some agricultural and domestic workers may not be covered. To qualify, the injury or illness must be directly related to the job, whether it occurs on the work premises or off-site while performing work-related duties.
