The BBC is reporting that striking Boeing workers are set to vote on a new offer from the aviation giant, which includes a 38 per cent pay rise over the next four years.
The International Association of Machinists and Aerospace Workers, IAM, the union which represents more than 30,000 striking workers, has endorsed the offer and says it will hold a ballot of its members on Monday.
The walkout started on September 13, leading to a dramatic slowdown in production and deepening a crisis at the firm.
The union had previously called for a 40 per cent pay increase and workers have rejected two previous offers, including the last offer of a 35 per cent rise.
As well as the proposed pay rise, the latest offer includes a US $12,000 bonus for the workers if a deal is reached, up from US $7,000.
