The union representing thousands of striking Boeing workers, the International Association of Machinists and Aerospace Workers (IAM), has reported that a recent survey indicates its members are "not interested" in Boeing's latest pay proposal. The IAM stated in a post on X that many comments from members deemed the offer "inadequate."

Boeing had recently submitted a new offer, proposing a 30% pay increase over four years, alongside the reinstatement of a performance bonus, enhanced retirement benefits, and a one-time signing bonus of $6,000 (£4,470). The company described this as its "best and final" offer, which requires ratification by union members by midnight Pacific Time on Friday, September 27 (7:00 GMT on Saturday, September 28).

However, the IAM expressed frustration that Boeing had communicated the offer directly to union members and the media without prior notification to union representatives. The union argued that the timeline set by Boeing did not allow sufficient opportunity for a member vote.

Boeing refuted claims that it had neglected to inform IAM representatives, asserting it would provide the union with additional time and logistical support for conducting a vote among its members.

More than 30,000 Boeing workers have been on strike since September 13, following the rejection of a previous 25% pay increase offer. The IAM initially sought a 40% pay raise, and union members who manufacture aircraft like the 737 Max and 777 overwhelmingly supported the strike action until a satisfactory agreement is reached.

The ongoing strike poses a significant financial threat to Boeing, which is already grappling with considerable challenges, including the suspension of jobs for tens of thousands of staff.
