Boeing makes a new offer to the union in hopes of ending a strike now in its second month

Boeing and the union representing striking machinists have negotiated a new contract proposal that would provide bigger pay raises and bonuses in a bid to end a costly walkout that has crippled production of airplanes for more than a month.

The International Association of Machinists and Aerospace Workers said early Saturday that it plans to hold a ratification vote on Wednesday.

The union said the deal would increase pay by 35% over four years, up from 30% that was offered last month. It also boosts the ratification bonus to $7,000 per worker instead of $6,000.

The new offer would not restore a traditional pension plan - a key demand of the 33,000 striking workers - but it would increase the amount of contributions to 401(k) retirement plans that Boeing would match and retain performance bonuses that Boeing wanted to eliminate, the union said.

“The fact the company has put forward an improved proposal is a testament to the resolve and dedication of the frontline workers who’ve been on strike - and to the strong support they have received from so many,” union district presidents Jon Holden and Brandon Bryant said in a statement.

“We look forward to our employees voting on the negotiated proposal,” Boeing said.

The union credited acting Labor Secretary Julie Su for helping produce the new proposal. Su met with company and union officials this week in Seattle in an indication of the Biden administration’s concern about the strike’s impact on the economy.

About 33,000 members of IAM District 751 began a strike on Sept. 13 after more than 94% voted to reject a Boeing offer that was supported by union leadership.

The strike by workers in Washington state, Oregon and California has halted production of Boeing 737s including the 737 Max, and 767s and 777s. Boeing is continuing to build 787 Dreamliners at a nonunion plant in South Carolina.

The strike has led new Boeing CEO Kelly Ortberg to announce about 17,000 layoffs and take early steps toward raising up to $25 billion from new stock or debt to bolster the company’s finances.

Boeing suppliers are feeling the pinch, too. Spirit AeroSystems, which builds fuselages and other components for Boeing planes, said Friday that it will put 700 workers on three-week furloughs beginning later this month and will resort to layoffs if the Boeing strike continues past November.
