AVIATION giant Boeing has withdrawn its 30 per cent pay rise offer to striking staff in the US after negotiations with union representatives reached a stalemate.

The company said today that the union was not giving its proposals serious consideration.

But the International Association of Machinists and Aerospace Workers (IAM) said Boeing was “hell-bent on standing on the non-negotiated offer” which was sent directly to the media on September 23 and which its members rejected.

“They refused to propose any wage increases, vacation/sick leave accrual, progression or ratification bonus,” it said in a statement.

“They also would not reinstate the defined benefit pension.”

The union, which represents the 33,000 striking workers, also stated that making offers through the media was making it harder to reach an agreement.

Boeing has suspended the jobs of tens of thousands of staff in response to the walkout which began on September 12, shutting down production of some planes.
