Outside city workers with Local 18 are another group not pleased with the pension reforms that makes deeper cuts, including the suspension of indexing.
President Mike Meahan says the union doesn't understand why the province rejected the first reform package, which was agreed upon by all the working groups.
He says clawing back benefits from retirees is a tough pill to swallow and he says his union will not accept it.
He says the union will be trying to meet with the province and MLA's to continue to push the first option.
