Aerospace company Boeing’s announcement that it is suspending production of the 737 MAX passenger jet is affecting more than just the business’s financial results. Thousands of employees and hundreds of suppliers are also facing an unclear future with the production freeze, Boeing’s biggest in 20 years. Boeing builds the 737 MAX in Seattle, Washington. About 12,000 employees are involved in making the airplane. The company said it would not lay off employees during the production freeze. However, the move will affect a supply chain of up to 900 companies in the U.S. and overseas that make parts for the complex jet. Boeing’s board of directors made the decision Monday after a two-day meeting. Last week, the Federal Aviation Administration did not approve the 737’s return to service before 2020.
