In Wichita, Kansas, nearly half of the roughly 10,000 employees at aircraft companies Textron Inc and Spirit AeroSystems remain unvaccinated against COVID-19, risking their jobs in defiance of a federal mandate. "We're going to lose a lot of employees over this," said Cornell Beard, head of the local Machinists union district. Many workers did not object to the vaccines as such, he said, but were staunchly opposed to what they see as government meddling in personal health decisions. The clock is ticking for companies that want to continue gaining federal contracts under an executive order by Democratic President Joe Biden, which requires all contractor employees be fully vaccinated against COVID-19 by Dec. 8. That means federal contract workers need to have received their last COVID-19 shot at least two weeks before the deadline to gain maximum protection, according to U.S. government guidance. Opposition to the mandate could potentially lead to thousands of U.S. workers losing their jobs and imperil an already sluggish economic recovery, union leaders, workers and company executives said. At a rally last week outside Boeing property in Auburn, south of Seattle, many of the three dozen workers gathered in driving rain said they would rather be escorted off Boeing property on Dec. 8 than take a vaccine. Others said they would pursue early retirement. "The mandate is illegal, immoral and impractical," said one veteran Boeing program analyst who attended the rally.
