The airline will become the first major US company to levy a penalty for unvaccinated employees, according to Bloomberg.

The new policy was outlined in a company memo Wednesday from Chief Executive Officer Ed Bastian, who said 75% of the carrier's workers already are vaccinated. Increasing cases of coronavirus linked to a "very aggressive" variant are driving the push for all employees to get the shots, he said. -Bloomberg

Unvaccinated employees have until November 1st to get the jab, while the company will also mandate weekly testing for anyone not vaccinated by mid-September.
