Workers' compensation covers a wide range of injuries and illnesses that occur as a result of employment. This includes acute injuries from accidents (such as slips, trips, and falls), repetitive stress injuries (like carpal tunnel syndrome), occupational illnesses (such as respiratory diseases from exposure to harmful substances), and psychological conditions stemming from work-related stress or trauma. Essentially, any injury or illness that can be directly linked to job-related activities or conditions is typically covered.
