CPS teachers are seeking state support to increase The Chicago Teachers Pension Fund (CTPF), which is currently underfunded by millions of dollars. Senate Bill 3628 would allow $270 million to flow into the CTPF but, after that, state contributions would fall to ten percent of what it provides to the Teachers Retirement Fund, which is for teachers outside of Chicago. If the bill were to pass the senate it would still need to find support in the Illinois House. Controversial spending by the Teachers Retirement System (TRS) of Illinois adds an element of question to the debate.
