SEATTLE (AP) — Blue-collar workers from Boeing are walking picket lines in the Pacific Northwest instead of building airplanes after overwhelmingly rejecting a proposed contract that would have raised their wages by 25% over four years. The strike by 33,000 machinists that started on Friday will not disrupt airline flights anytime soon, but it is expected to shut down production of Boeing’s best-selling jetliners. And it marks yet another setback for a company already dealing with billions of dollars in financial losses and a damaged reputation. Boeing says it’s taking steps to conserve cash while the company’s new CEO looks for ways to come up with a contract that union members will accept.
