Aerospace firm Boeing doesn’t expect to reach production of 42 737 MAX jets a month until early 2025, about six months later than originally planned.

Boeing's U.S. West Coast factory workers walked off the job on Friday after overwhelmingly rejecting a contract deal, halting production of the planemaker's strongest-selling model and sending shares down over 2%.

Thirty thousand workers at Boeing go on strike for wages and benefits, endangering the company's ability to recover from $60 billion in debt and safety concerns.
