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.

The union complained that Boeing publicized its latest offer to 33,000 striking workers without first bargaining with union negotiators.

“Boeing does not get to decide when or if you vote,” leaders of the International Association of Machinists and Aerospace Workers district 751 told members Monday night. “The company has refused to meet for further discussion; therefore, we will not be voting” on Friday, as Boeing insisted.
