NEW YORK (AP) — Saying “enough is enough,” thousands of workers at three Boeing manufacturing plants went on strike overnight less than a year after the company boosted wages to end a separate, 53-day strike by 33,000 aircraft workers.

Boeing union workers who assemble fighter jets strike in two states following rejection of contract offering 20% general wage increase and $5,000 bonus.

Workers at three manufacturing plants walked off the job after turning down a proposed labor deal that included pay increases and bonuses.
