U.S. employers wrestle with COVID vaccine requirements in regulatory "hairball"

America's largest garlic farm needs 1,000 workers to harvest its annual crop, but faces an unexpected hurdle in this year's recruitment drive: it now must document and track the COVID-19 vaccine status of these seasonal laborers. Employers in California's Santa Clara County, including Christopher Ranch, are required as of June 1 to ascertain if their workers have been vaccinated and check in every 14 days on those who say they have not or who decline to answer.
