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.

It’s not clear how many metro-east jobs are impacted by the strike. Boeing moved 150 jobs from facilities throughout St. Louis and expected to create 150 new jobs for engineers, mechanics and other staff once the facility became fully operational.

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