More than 30,000 Boeing machinists walked off the job Sept. 13. At a local union office outside Seattle, they prepared for what may be a lengthy strike.

Boeing workers in Washington went on strike this week as new CEO Kelly Ortberg purchased a $4.1 million mansion in a gated community in Seattle.

Boeing faces a potentially crippling strike in the Seattle region, depending on how 33,000 workers vote Thursday on a new contract that has angered many employees despite solid wage gains.
