Disability Insurance, often called DI or disability income insurance, or income protection, is a form of insurance that insures the beneficiary's earned income against the risk that a disability creates a barrier for a worker to complete the core functions of their work. For example, the worker may suffer from an inability to maintain composure in the case of psychological disorders or an injury, illness or condition that causes physical impairment or incapacity to work.
