Social Security Disability Insurance (SSDI) requires that you have worked and paid into Social Security through payroll taxes. This category explains work credits—what they are, how you earn them, and how many you need to may have access to for SSDI. Understanding these requirements helps you see whether your work history meets what Social Security looks for.
