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.

Union members who assemble Boeing's fighter jets in the St. Louis area have "overwhelmingly voted" to reject the company's contract offer on Sunday, with the company now preparing for an imminent strike.

Boeing Co. expects more than 3,200 union workers at three St. Louis-area plants that produce U.S. fighter jets to strike after they rejected a proposed contract Sunday that included a 20% wage increase over four years.
