Some 33,000 Boeing workers in Washington state and Oregon are walking off the job after overwhelmingly rejecting a new contract. It’s Boeing’s first strike in 16 years and will halt production on most of its aircraft, including its troubled 737 MAX. Workers are seeking pay raises of 40%; the tentative agreement only pledged to raise wages by 25%.

In related news, hotel workers in Boston, New Haven and San Diego have launched the second wave of a phased strike that started at hotels around the country on Labor Day.
