SSDI stands for social security disability insurance. SSDI is defined as:

“Social Security Disability Insurance (SSDI) is a payroll tax-funded, federal insurance program. A portion of the FICA taxes you pay are set aside for SSDI (as well as Social Security Retirement and Medicare). SSDI, which was established in 1954, is designed to provide you with income if you are unable to work due to a disability or until your condition improves, and guarantees income if your condition does not improve. Then once you meet your retirement age – 65 or older – you move from SSDI to Social Security retirement income.”

It is incredibly important. SSDI is especially important for people who work in positions that include manual labor. Construction workers, etc…something could happen on the job and then what would happen? See, situations like that is where SSDI comes into play. It is so important to have plans like this…you just never know when something could go wrong.
