CHICAGO (CBS) — Mayor Emanuel and labor leaders have announced settlement on a new Police Sergeants’ contract that he hopes can be a framework for a larger police union agreement.

James Ade, head of the Police Sergeants’ Association said the tentative agreement calls for higher pension fund contributions and periodic freezes in cost of living increases but a nine percent pay hike over four years and he admitted it is a tough sell.

“It is a tough one you know, but as leadership of a union, we are there to make tough decisions,” said Ade.

Mayor Emanuel said it would secure the pensions for the 1,200 sergeants and he hopes it can serve as a model for the 17,000 member Fraternal Order of Police, representing rank and file cops.

“Every union agreement will be different, but all agreements to secure the retirement security of the contract agreement will have these parts,” said Emanuel.

The union members and city council must ratify must ratify the agreement.
