Over 30 years of retirement, Shannon would collect as much as $209,116, according to a projection by Local Government Information Services (LGIS), which publishes Chicago City Wire.
The projection assumes Shannon received $4,395 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 4 years of retirement, Shannon will have already received $18,388 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
