United Airlines declared Friday that it will require the entirety of its US employees to get vaccinated against COVID-19 by the fall, turning into the principal major airline to do as such.

The Chicago-based airline’s 67,000 US employees should be vaccinated by no later than Oct. 25 or risk termination, CEO Scott Kirby and President Brett Hart said in a letter to employees Friday.

“We know some of you will differ with this decision to require the vaccine for every United worker,” the executives wrote. “However, we have no more noteworthy obligation to you and your partners than to guarantee your safety when you’re grinding away, and the realities are perfectly clear: everybody is more secure when everybody is vaccinated.”

“Throughout the most recent 16 months, Scott has sent many sympathies letters to the family members of United employees who have kicked the bucket from COVID-19. Not really set in stone to do all that we can to attempt to hold another United family back from getting that letter,” the letter went on.

Employees who get vaccinated and give proof to United before Sept. 20 will get an extra day of pay, also, the letter said.

The company said employees should transfer proof that they got either two dosages of the Pfizer or Moderna vaccines, or one portion of the Johnson and Johnson shot. Laborers have until five weeks after the Food and Drug Administration offers full endorsement to the chances or by Oct. 25, whichever is first, the letter added.

A United representative added that there will be “an exceptionally tight sensible accommodation process (as legally necessary) for strict and clinical exclusions.”

“We’ll deal with those dependent upon the situation and in case anybody is conceded a special case, they should be masked consistently,” they said.

United executives have since quite a while ago urged employees and clients to get vaccinated.

Since June, United has required all recently recruited employees to be vaccinated, yet avoided commanding the shots for the whole workforce.

United’s decision comes after an influx of major businesses have declared comparative orders for their workforces as the Delta variant of the Covid sends instances of COVID-19 taking off.

Tech companies, including Facebook and Microsoft, have said employees should be vaccinated to get back to the office. Walmart, the country’s biggest boss, declared last week that corporate staff and managers should get vaccinated.
