Boeing is making what it calls a "best and final offer” to striking union machinists, but the union says it won't vote by Boeing's deadline.

Boeing said Monday it made a "best and final offer" to striking machinists that includes bigger raises and larger bonuses, but the workers' union said the proposal isn't good enough and there won't be a ratification vote before Boeing's deadline at the end of the week.

Boeing Co. took a 30% pay-bump proposal directly to striking workers, as the embattled planemaker seeks to chart a path out of a debilitating strike that has shut down factories across the Pacific Northwest for more than a week.
