Boeing 777X certification at risk if engineers strike
Boeing engineers, represented by SPEEA, voted 88% in favor of striking after rejecting an initial contract proposal. Boeing offered a revised deal with a 10% wage increase. A strike could delay the 777X certification, impacting deliveries to Emirates, Qatar Airways, and Cathay Pacific, and disrupt 737 MAX production.
