Over 30 years of retirement, Williamson would collect as much as $632,916, according to a projection by Local Government Information Services (LGIS), which publishes Illinois Valley Times.
The projection assumes Williamson received $13,303 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 4 years of retirement, Williamson will have already received $55,654 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
