Striking machinists accepted a new contract raising wages by 39 percent, but enduring bitterness will complicate Boeing’s efforts to rebuild its battered corporate culture and flawed production process.

Seattle — Unionized machinists at Boeing voted Monday to accept a contract offer and end their strike after more than seven weeks, clearing the way for the aerospace giant to resume production of its bestselling airliner and generate much-needed cash.

The Boeing Company and the International Association of Machinists and Aerospace Workers union agreed to a new contract to officially end the 7-week strike.
