IAM 751 tonight approved a new, four-year contract with The Boeing Co, extending labor peace to 2016. The union and the company negotiated the contract nearly a year early, an unprecedented move in Boeing-IAM relations.

The vote passed with a votes of 74%.

The union gets raises, a signing bonus, and assurances Boeing will build the 737 MAX in Seattle (though the contract language isn’t actually rock-solid definitive). The union will tell the NLRB it wants to drop the complaint over the Charleston 787 assembly site.
