Chicago Mayor Rahm Emanuel reached an agreement with unions on a way to shore up the smallest of the city’s struggling pension funds, saying it would create a “path to solvency” after a previous overhaul was struck down by the Illinois Supreme Court, Bloomberg News reported yesterday. The city and two unions reached a pact that — if finalized — would aid a pension that’s set to run out of money by 2029. The deal would require an increase in contributions from employees who want to retire as early as 65 and boost Chicago’s payments into the Laborers’ and Retirement Board Employees’ Annuity and Benefit Fund by no less than 30 percent a year over five years, beginning with the contribution due in 2018. The fund serves some 8,000 employees, retirees and beneficiaries.
