Sixty-four percent of members of the International Association of Machinists and Aerospace Workers (IAM) union reported they voted against the proposed agreement.
After an earlier offer was turned down, more than 30,000 Boeing workers joined the walkout, which began on September 13.
Kelly Ortberg, the CEO of Boeing, issued a warning a few hours ago that the corporation is at a “crossroads” after losses jumped to about $6 billion (£4.6 billion).
In a statement, union representatives stated, “We still have ground to make up after ten years of sacrifices, and we’re hopeful to do so by resuming negotiations promptly.”
In addition to being unmistakable proof that there are repercussions when a business consistently mistreats its employees, it stated that this is workplace democracy.
Boeing has refrained from commenting on the rejection of its most recent offer.
The striking employees have officially voted down a potential agreement for the second time. 95% of employees rejected the prior offer last month.
Prior to this, Mr. Ortberg, who became CEO in August, claimed to have been working “feverishly” to stabilize the company as it attempted to restore its reputation after manufacturing and safety concerns damaged it.
