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

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.

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.
