Boeing Engineers Authorize Potential Strike as 737 Output Reaches Multi-Year High

Boeing is pushing 737 assembly line output to its highest levels in years, even as a potential labor disruption looms over its technical workforce, Yahoo Finance reported. The company started moving toward a monthly output target of 47 narrowbody jets during the second quarter and added a new manufacturing line in July, accelerating a recovery following prolonged regulatory restrictions.

That manufacturing momentum faces potential headwinds after members of the Society of Professional Engineering Employees in Aerospace (SPEEA) rejected Boeing's contract proposals on Aug. 21. Representing approximately 17,000 engineers and technical personnel, the union's professional group voted 64 percent against the offer, while the technical group rejected it by 72 percent. Both divisions granted strike authorization by margins of 88 percent and 90 percent, respectively, ahead of contract expirations set for midnight on Oct. 6.

In response to the vote, Boeing executive leadership indicated that organizational preparations for a work stoppage are underway. "We are now implementing our strike contingency plan and diverting the dollars we had wanted to invest in our SPEEA-represented team to prepare for a potential strike," said Ben Nimmergut, Boeing’s vice president and functional chief engineer for production engineering. According to reporting from Leeham News, Boeing has begun listing employment opportunities for temporary replacement engineers, while union leadership and corporate negotiators are scheduled to resume discussions on Monday following union survey feedback.

While SPEEA staff do not assemble physical jets on the factory floor, their technical expertise supports assembly operations, quality oversight, and regulatory filings. Boeing secured Federal Aviation Administration certification for its 737-7 aircraft on Aug. 3 and is working toward approval for the larger 737-10 variant. A prolonged dispute could slow down technical support necessary to maintain the 47-per-month production schedule and delay ongoing aircraft certification milestones.

The labor tension arrives alongside improving top-line financial metrics. Boeing delivered 171 commercial planes in the second quarter, marking a 14 percent gain over the 150 units delivered in the prior-year period. Quarterly revenue increased 8 percent to $24.6 billion, while non-GAAP free cash flow turned positive at $631 million, reversing a $200 million cash drain recorded a year earlier. The manufacturer's adjusted core loss per share narrowed to $0.76 from $1.24 in the same period last year.

Despite positive operational cash flow, Boeing's balance sheet remains heavily leveraged, carrying $45.9 billion in total debt against $20 billion in cash and short-term investments. Commercial demand continues to outstrip immediate assembly output, pushing Boeing's order backlog to a record $715 billion, which includes more than 6,200 commercial airliners. Regulators previously restricted 737 output to 38 planes per month in January 2024 following an in-flight door plug failure on a MAX 9 jet, before approving an increase to 42 last autumn and granting permission for 47 jets monthly earlier this year.

The upcoming contract deadline follows significant recent labor turbulence for the manufacturer, including a seven-week strike in September 2024 involving more than 32,000 machinists. Boeing shares have recently traded near $210, down roughly 17 percent from their 52-week peak of $254.35, valuing the company at approximately 1.74 times sales as negotiations continue toward the Oct. 6 deadline.
