Boeing’s Engineers Reject a Contract and Vote to Authorize a Strike

On August 21, 2026, members of SPEEA, Boeing’s largest white-collar union, rejected the company’s contract offer and voted to authorize a strike if no new deal is reached before their contracts expire on October 6.

SPEEA’s Professional Unit, nearly 13,000 engineers and scientists, voted the contract down 64.3% to 36%, a margin of 7,238 to 4,027. The Technical Unit, more than 4,000 designers, analysts and technicians, rejected its terms even more decisively, 71.9% to 28%.

Strike authorization passed by wide margins in both groups: 87.8% among professionals and 89.7% among technicians. A strike cannot legally begin before October 7, the day after the current contracts expire.

What was on the table

Boeing’s rejected offer included average pay increases of nearly 30% over four years, which the company called its largest wage increase in 40 years, plus three extra days of paid leave, lower mandatory-overtime caps and more virtual-work options.

Members voted it down anyway. SPEEA’s negotiating team said in a statement that “your voices and votes have made clear that the proposed contract terms fall short for members and that negotiations with Boeing must continue.”

Boeing responded the same day by withdrawing two sweeteners it had offered for early ratification: a 3% wage increase retroactive to February, and a 40% boost to the 2026 incentive-payout target. Ben Nimmergut, Boeing’s vice president and functional chief engineer for production engineering, told members the company is “diverting those dollars to execute our plan and prepare for a potential strike.”

Why this group matters to Boeing’s schedule

SPEEA members are not on the factory floor. They design, analyze and verify aircraft across the 737 MAX and 777X, KC-46 and P-8 programs, and some hold Boeing’s delegated authority to certify aircraft on the FAA’s behalf.

That delegated authority, known as ODA, is the same certification pipeline the FAA recently let Boeing resume using for the 737 MAX and 787. A prolonged walkout by the engineers who staff it could slow the ongoing 737 MAX 10 and 777-9 certification campaigns even if Boeing’s assembly lines keep moving.

Neither side has set a date for new talks as of this writing. Both unions’ contracts remain in force until October 6, and a strike is a legal option after that date, not a certainty.

SPEEA has walked out only twice before: a one-day protest in 1993, and a 40-day strike in 2000 that won members contract gains once mediators brought both sides back to the table. Whether this round follows that pattern likely depends on what Boeing puts on the table once talks resume.
