Boeing Co. will temporarily stop producing its grounded 737 Max jet starting in January as it struggles to get approval from regulators to put the plane back in the air. The company says it will halt production at its plant with 12,000 employees in Renton, Washington, near Seattle. It says, however, it doesn’t immediately expect any layoffs as a result of the production halt. But layoffs could ripple through some of the 900 companies that supply parts for the plane. The Max has been grounded since March after two deadly crashes.
