Over 30 years of retirement, O'Brien would collect as much as $958,914, according to a projection by Local Government Information Services (LGIS), which publishes South Cook News.
The projection assumes O'Brien received $20,155 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 4 years of retirement, O'Brien will have already received $84,322 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
