The city's fire and police sworn personnel make up about 80% of the total pension costs. Barrett said the city is looking at the structure of the pension system for all other police officers and firefighters throughout Wisconsin as a potential template for the city's package for those departments. Milwaukee and Milwaukee County are separate from the state's retirement system. The city is interested in having parity with the Wisconsin retirement system, Barrett said. "We are faced with the notion of having a dramatic increase in the pension payment on the horizon, (and) a law that does not allow us to renegotiate this unless we do it through collective bargaining," Barrett said. Shawn Lauda, president of the Milwaukee Police Association, said he believes the parity is already there. He said the union has made concessions.
