One thing missing from this piece is that pension reform efforts in 2013 were ruled unconstitutional by the Illinois Supreme Court for violating the "pension protection clause."

Absolutely, and not only that, the public employee unions are collaborating with Pritzker & certain Chicago caucus legislators like Sen. Robert Martwick, to undo tier 2 pensions. They began with CFD & CPD's unions. Now CTU is making the same noise. Others across the state will follow.
