The union representing Boeing employees have begun a strike after about 3,200 workers at facilities in St. Louis and other locations voted to reject a modified four-year labor agreement.

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

More than 3,200 union members who assemble Boeing's fighter jets in the St. Louis area and Illinois went on strike on Monday after rejecting a second contract offer the previous day.
