Apple will require all employees to get a vaccine booster shot or submit to Covid tests.
A booster shot is part of staying up to date with your vaccine to protect against severe disease due to the waning efficacy of the primary series.
The media outlet said that Apple employees who are eligible for booster shots have four weeks to get jabbed or take rapid antigen tests before entering the workplace.
The memo shows that those who are unvaccinated must provide negative test results from January 24. It wasn't immediately clear if this testing requirement applies to retail and corporate employees.
Apple didn't reply immediately to Insider's request for comment.
