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.

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

Some 3,200 Boeing workers who build fighter jets in St. Louis, another Missouri site and one in Illinois are on strike, their union says.
