Striking Boeing workers are expected to vote on a new offer from the aviation giant, which includes a 38% pay increase over the next four years.
The International Association of Machinists and Aerospace Workers (IAM) union, which represents more than 30,000 striking workers, approved the offer and said it would hold a vote among its members on Monday.
The walkout began on September 13, causing a dramatic slowdown in production and deepening the crisis within the company.
Two previous offers from Boeing were rejected by strikers who demanded a 40% pay increase.
As well as the proposed pay rise, the latest offer includes a $12,000 (£9,304) bonus for workers if a deal is reached, up from $7,000 in the previous offer.
“It is time for our members to consolidate these gains and declare victory with confidence,” the IAM said on social media.
“We believe that asking members to remain on strike any longer would not be a good thing given that we have had so much success.”
“We encourage all of our employees to learn more about the enhanced offer and vote on Monday, November 4,” Boeing said in a statement.
Shares of Boeing rose 2.7% in after-hours trading in New York following the news.
