Boeing Co. has resumed contract talks with leaders of the union representing some 3,200 factory workers in the St. Louis area, after members resoundingly rejected its initial offer and voted to strike.

Boeing's defense division is expanding manufacturing facilities in the St. Louis area for the new U.S. Air Force fighter, the F-47, after it won the contract this year.

Boeing is facing another labor strike just months after resolving a contract dispute with workers in the Pacific Northwest. This stoppage could impact the defense business.
