Boeing Strike by 3,200 Machinists Cuts Defense Output, Stock Slides 1.3%

Boeing (NYSE: BA) got hit hard Monday as about 3,200 machinists from IAM District 837 launched a strike, pushing shares down roughly 1.3%. The union members, who've been chafing over contract terms, rejected Boeing's second offer, signaling they're not about to back down anytime soon.

The strike kicked off at midnight Central Time and covers workers who build fighter jets like the F-15 and F/A-18, along with other defense gear. This crew makes up around 2% of Boeing's workforce, which amplifies the disruption's potential ripple effect on defense production.

The union's "no" comes after a cooling-off period that started on July 27, following the first deal Boeing pitched earlier this summer. Tom Boelling, the union's top dog, said the members want a deal that truly values their skills and role in national defense. No subtle hints there-this is about respect and pay.

Boeing's latest offer wasn't shabby on paper: a 20% wage increase stretched over four years, kicking off with an 8% bump in year one, then 4% annually after that. Add a $5,000 ratification bonus, more time off, pension upgrades, and a $0.50 per hour attendance bonus, plus scrapping the unpopular alternative workweek schedules.

Crunching the numbers, this would have pushed average annual pay from $75,000 to $102,600, burning about $70 million for Boeing once bonuses and raises rolled in. Still, the union wasn't convinced.

This isn't Boeing's first rodeo with strikes lately. Local 751 machinists staged a walkout last September, wrapping up after the company wheeled out a 38% pay hike and a hefty $12,000 bonus in November. That round clearly set a precedent, raising the bar for what the IAM District 837 crew is after.

Monday's strike sent Boeing shares lower as markets factored in the hit to production timelines and the broader defense contracts. For a company deeply intertwined with U.S. military output, these delays could bite beyond the immediate labor dispute.

The next moves? That's anyone's guess. But the strike underscores the tightrope Boeing's walking-balancing rising labor costs with production demands in an unforgiving market.
