Boeing Engineers Reject Contract by 64%, Authorize Strike as Mistrust Deepens

Engineers and technicians at Boeing have overwhelmingly rejected a four-year contract proposal that their own negotiating teams had unanimously recommended, setting the stage for a potential labor stoppage at the troubled aerospace giant. The 17,000 members of the Society of Professional Engineering Employees in Aerospace (SPEEA) voted down the tentative agreement by decisive margins, with engineers rejecting it by 64.3% and technicians voting against it by 71.9%.

In a separate ballot, union members authorized strike action if no contract is approved by October 6, when current agreements expire. The strike authorization passed with even stronger support, garnering 87.9% approval from engineers and 89.7% from technicians. SPEEA represents Boeing’s largest white-collar union workforce, making any work stoppage a significant threat to the company’s already-delayed certification campaigns for the 737 Max 10 and 777-9 aircraft, both of which are running several years behind schedule.

The rejection comes despite both the negotiating teams and Boeing praising the talks for their collaboration and civility. The tentative agreements were reached after less than a month of negotiations, with Boeing labeling them as its “Best and Final Offers” (BAFOs). However, union leadership pointed to deep-seated problems that undermined member confidence in the proposals.

Mistrust Built Over Decades

“It became clear that SPEEA members deeply mistrust Boeing management,” SPEEA said in a statement following the vote results.

The union’s leadership attributed the rejection to accumulated grievances spanning multiple contract cycles. SPEEA noted that this mistrust was “built brick-by-brick over the past several contracts” and characterized it as the result of decades of bad management. While the negotiating team endorsed the terms, neither of SPEEA’s bargaining unit councils backed the offer, signaling internal discord over the proposal’s adequacy.

The company did not immediately respond to requests for comment following the vote announcement. In July, Boeing CEO Kelly Ortberg had told Wall Street analysts that the company began discussions early “to work towards an agreement that supports our employees and their families, creates greater clarity for our business and helps us stay focused on the progress we’re making.”

Inflation Cap Sparks Anger

Boeing’s offer included wage increases tied to inflation, but with a critical limitation: the inflation-based raises were capped at 3%. The company also proposed increases based on individual performance and other unspecified metrics determined by Boeing. Several SPEEA members who voted to reject the offer told media outlets that the inflation cap would nearly guarantee their salaries fall behind actual cost-of-living increases.

The concern appears well-founded based on recent economic data. The Consumer Price Index, a key inflation benchmark, rose 4.5% over the past year for the Seattle area, where most SPEEA members work, according to the U.S. Bureau of Labor Statistics reporting from July. With inflation running half a percentage point above the proposed cap, workers faced the prospect of real wage erosion even with the contract’s built-in increases.

The engineers and technicians units negotiate together with Boeing, but they vote separately on contract proposals. Both groups must approve an agreement for it to take effect. The company offered better terms than expected, several union members acknowledged, yet the gap between the offer and member expectations remained too wide to bridge.

Echoes of 2024 Strike

The rejection mirrors a pattern from recent Boeing labor negotiations. In 2024, contract talks between Boeing and its touch-labor union, the IAM 751, produced a tentative agreement that both Boeing and union leadership described as the best ever. Union members defeated that contract with an 85% vote and authorized a strike with an 86% vote on the same day the contract expired.

The roughly 33,000 members of the International Association of Machinists and Aerospace Workers went on strike at midnight on September 12 and stayed out for 53 days, bringing Boeing commercial airplane production in the Seattle area to a halt for seven weeks. Boeing made three more offers during that stoppage, with the fourth becoming its actual final offer, which union members ultimately accepted.

Next Steps in Negotiations

SPEEA leadership plans to take a few days to survey members before requesting new talks with Boeing, potentially as early as next week. The union emphasized its dual preparedness for both negotiation and potential action.

“Our Negotiation Team is prepared and willing to work with the company toward meaningful movement so that we can come to agreement on new contracts before Oct. 6,” SPEEA said in a statement. “However, we also are prepared to call for a labor stoppage, based on the overwhelming support of our members for the strike authorization vote.”

Importantly, no strike is currently permitted because the existing contracts remain in place. The October 6 expiration date serves as the key deadline driving the timeline for renewed negotiations. Both sides now face pressure to find common ground before that date arrives, with the strike authorization vote demonstrating workers’ willingness to walk out if their concerns remain unaddressed.

A work stoppage by SPEEA members would compound Boeing’s operational challenges at a critical time. The company continues struggling to advance certification for key aircraft programs while managing quality issues and regulatory scrutiny. The loss of engineering and technical support would further delay these certification campaigns, potentially costing the company additional revenue and market position against competitors.

Although Boeing labeled the rejected proposals as its Best and Final Offers, history suggests room for movement remains. It is rarely the case that a true final offer arrives with the first tentative agreement, and the 2024 experience with IAM 751 demonstrated Boeing’s willingness to make multiple improved offers when faced with determined workforce opposition. The coming weeks will reveal whether the company adopts a similar approach with its white-collar technical workforce.
