Receiving pension
Depending on the type of job they have, not all people are eligible for Social Security. This is especially valid if you receive some sort of pension.
“Not every worker pays into the Social Security system. In certain states, public employees are not covered by Social Security due to receiving a pension. They can include employees of state and local government agencies, including school systems, colleges and universities. In some states, they may also include police officers and firefighters.”
