The Society of Professional Engineering Employees in Aerospace technical unit approved the latest contract offer from Boeing, ending months of negotiations between the union and the company.

When the votes were all tallied Monday evening, the vote came to 4,244 to accept and 654 to reject, an approval rate of more than 86 percent.

The contract they approved was the same contract the unit rejected last month. The union’s professional unit approved the contract during that vote, but the technical unit rejected it.

The sticking point was the company’s move to place all new hires into a 401K program instead of the company’s pension plan.

When negotiators picked up again between the two sides, Boeing put forth the exact same offer.

Technical workers have been without a contract since Nov. 25.
