Striking Boeing workers are set to vote on a recent propose from the aviation giant, which includes a 38% pay rise over the next four years.

The International Association of Machinists and Aerospace Workers (IAM) union, which represents more than 30,000 striking workers, has endorsed the propose and says it will hold a ballot of its members on Monday.

The walkout started on 13 September, leading to a dramatic slowdown in production and deepening a crisis at the firm.

The union had previously called for a 40% pay boost and workers have rejected two previous offers, including the last propose of a 35% rise.

As well as the proposed pay rise, the latest propose includes a $12,000 (£9,300) bonus for the workers if a deal is reached, up from $7,000.

“It is period for our members to lock in these gains and confidently declare win,” an IAM social media post said.

“We depend asking members to remain on strike longer wouldn’t be correct as we have achieved so much achievement.”

Boeing said the propose would view average annual pay rise to $119,309 over the next four years.

“We inspire all of our employees to discover more about the improved propose and vote on Monday, November 4,” Boeing said in a statement.

The recent propose also includes changes to workers’ superannuation plans.

Boeing shares rose 2.7% in extended buying and selling in recent York after the proposed deal was announced.

Boeing has been trying to complete the strike, which has now expense it nearly $10bn according to consulting firm Anderson Economic throng, and shore up its finances.

Last week, its commercial aircraft business reported operating losses of $4bn for the three months to the complete of September.

The business also launched a distribute sale to raise more than $20bn earlier this week.

It came after warnings that a prolonged strike could navigator to downgrades to Boeing’s borrowing rating, which would make it more expensive for it to borrow money.

The firm is also moving ahead with plans to lay off around 17,000 workers, with the first redundancy notices expected to be issued in mid-November.

The latest crisis at Boeing erupted in January with a dramatic mid-air blowout of a piece of one of its passenger planes.

Its space business also suffered a reputational hit after its Starliner vessel was forced to profit to Earth without carrying astronauts.
