Boeing workers have voted to accept the company’s latest pay offer, bringing an end to a seven-week strike that had significantly impacted operations.

The new contract grants workers a 38% pay increase over the next four years. The International Association of Machinists and Aerospace Workers (IAM) union announced that striking workers could begin returning to their jobs as early as Wednesday, with all back by November 12.

The strike, involving around 30,000 workers since September 13, led to a notable production slowdown at Boeing’s factories, intensifying challenges for the company. IAM reported that 59% of members voted in favor of the deal, which includes a $12,000 one-time bonus and adjustments to retirement plans.

“Through this victory and the strike that made it possible, IAM members have taken a stand for respect and fair wages in the workplace,” said union leader Jon Holden. Initially, the union had sought a 40% pay increase, and workers had previously rejected two offers from Boeing.

Boeing’s CEO Kelly Ortberg acknowledged the difficulties of recent months, saying, “While the past few months have been challenging, we are all part of the same team. There is much work ahead to restore the excellence that defines Boeing.”

The strike’s importance prompted the White House to send acting U.S. Labor Secretary Julie Su to Seattle last month to aid in negotiations.
