Boeing workers to vote on authorization of potential strike

"What can you do to get a good contract?" International Association of Machinists and Aerospace Workers (IAM) Local 751 asks on its website. "Attend strike sanction vote on July 17th!"

The local represents nearly 32,000 people in the Seattle, Washington, region, with about 30,000 at Boeing plants in nearby Renton, where the US aerospace giant's 737 is assembled, and in Everett, where the 777 is put together. A strike would freeze activity at both factories.
