Three CNN staffers were fired for coming into the office while not being vaccinated against COVID-19.

In a memo from CNN head Jeff Zucker said “Let me be clear — we have a zero-tolerance policy for this,” he wrote. “You need to be vaccinated to come to the office. And you need to be vaccinated to work in the field, with other employees, regardless of whether you enter an office or not. Period.” He noted that, while CNN does not have a formal vaccine mandate, it expects parent company Warner Media to mandate it soon.

This move by CNN is an indication of a larger trend in ‘no jab, no job’’ requirement in workplaces. Another media organisation.

The Washington Postsaid last week it would mandate vaccinations for all employees and visitors to its offices, while companies such as Disney and Walmart have announced mandates for their workforces. On Tuesday, New York City became the first U.S. city to require proof of vaccination to enter most indoor spaces.
