Here in California, a 'deal' was made decades ago that if people paid into social security but changed jobs and began paying into a pension system--they would lose the social security they paid into. Actually, the SS is reduced by the amount you get in your pension. Example: teacher's retirement equals $2000/mth. social security equals $1800/th. In this case, you get no social security. zero. In California, I believe it was called the Windfall Act. It was enacted decades ago. Most teachers have only been teachers, so it does not affect them--but for a small group who only taught 25 years and before that did something else, it is devastating and unfair.
