Disability insurance typically covers both work-related and personal health conditions that prevent an employee from working, providing a portion of their income while they're unable to perform their job duties. This can include things like illnesses, injuries, or chronic conditions, regardless of whether they're related to work or not. The key difference between disability insurance and workers' compensation is that workers' comp only applies to work-related injuries or illnesses, whereas disability insurance is more comprehensive, covering a broader range of conditions that may not be work-related, so it's a more robust benefit for employees.
