07:05 AM EDT, 10/09/2024 (MT Newswires) -- Boeing ( BA ) has withdrawn its recent pay offer of a 30% raise to about 33,000 US workers as negotiations with the striking union broke down, media outlets reported Wednesday.

Boeing ( BA ) was quoted saying in multiple reports that the union's demands were "non-negotiable," while the International Association of Machinists and Aerospace Workers reportedly said the company was "hell-bent on standing on the non-negotiated offer."

"They refused to propose any wage increases, vacation/sick leave accrual, progression, ratification bonus, or the 401k Match/SCRC Contribution. They also would not reinstate the defined benefit pension," the IAM was quoted in a Reuters source.

The strike began on Sept. 13, reportedly costing the company $100 million a day in lost revenue.

Neither Boeing ( BA ) nor the union immediately responded to MT Newswires' requests for comment.

Shares of the company were down 1.6% in recent Wednesday premarket activity.
