Which companies are mandating COVID-19 vaccines for employees?

Some tech giants and Wall Street banks are requiring their workers to get Covid-19 vaccines to return to their offices. A few U.S. airlines are telling new hires they must get inoculated. Most big manufacturers aren’t mandating injections. Neither is one of the main Covid-19 vaccine producers.

Though many companies had long encouraged, rather than required, vaccines, a rising number of Covid-19 cases and the spread of the highly transmissible Delta variant has led to a shift in thinking among some corporate leaders, said Francine Katsoudas, Cisco Systems Inc.’s head of human resources.

“You just don’t feel like you can protect your employees to the extent that you want to, and it makes you then lean in a little bit to kind of raise the bar around your expectations,” Ms. Katsoudas said in an interview. “I think everyone was trying initially to just respect everyone’s perspective around what they want to do [on vaccines], but we know that if we do that, we could create a pretty serious situation.”

Cisco has required the limited number of employees working in its offices in July and August to be fully vaccinated, guidance it will likely extend into the fall as its offices reopen more broadly, Ms. Katsoudas said.

Here is a look at how companies are responding to the pandemic:

Technology
Google and Facebook Inc. said this week that they will require all employees at their U.S. campuses to be vaccinated. Google also said it is delaying its work force’s return to the office until mid-October, after the Alphabet Inc. subsidiary previously planned to get most staff back on campus at the end of September.

Apple Inc. last week delayed its return to the office until at least October. Apple also said this week that it would require employees in its corporate offices and workers in its stores to wear masks even if they have been vaccinated.

The marketing-and-sales platform provider HubSpot Inc. told U.S. employees this week that it would require vaccinations to access its U.S. offices, barring a religious or medical exemption.

Twitter Inc. is shutting down its offices in San Francisco and New York just two weeks after the social-media company reopened those offices on July 12. The company had required proof of vaccination for employees returning to the office.

Salesforce.com Inc. in April said vaccinated employees who voluntarily disclosed their status would be allowed back in offices in places such as San Francisco in groups of about 100 people at a time.

Banking
Morgan Stanley in June was among the first big employers to require employees be vaccinated before returning to offices. Other banks including Goldman Sachs Group Inc. and Wells Fargo & Co. have asked or required that employees disclose their vaccination status.

Airlines
United Airlines Holdings Inc. and Delta Air Lines Inc. said in the spring they would require newly hired employees to be vaccinated. While carriers have offered incentives including cash bonuses and extra vacation time, airlines have largely avoided requiring current employees to be vaccinated. Some pilots unions have said they want vaccines to remain optional.

Healthcare
AstraZeneca PLC isn’t requiring staff to have shots, but vaccination uptake has been “pretty good,” Chief Executive Pascal Soriot said Thursday. “We are encouraging employees to be vaccinated, but we haven’t made it, and we don’t intend to make it compulsory for now.”

The company, which makes a globally distributed Covid-19 vaccine in partnership with the University of Oxford, will remain flexible with managers deciding work-from-home policies, he said.

Manufacturing
General Electric Co. hasn’t required its employees to get vaccinated. GE started to educate and encourage workers early in the year to get vaccinated, including working with healthcare providers to ensure easy access to the vaccine. “At this point, we have no plans to make vaccinations mandatory,” CEO Larry Culp said Tuesday.

Boeing Co. also isn’t requiring vaccines. The aircraft maker said it encourages workers to get vaccinated and has a system where employees can volunteer to share their vaccine status. Those who are fully vaccinated aren’t required to wear masks on worksites, while those who aren’t must wear masks, a spokeswoman said.

Hospitality
Cruise-line operators, seeking to resume sailing in the U.S., were among the first big employers to require staff to get vaccinated. Norwegian Cruise Line Holdings Ltd. said in April that it would require full vaccinations for all crew and passengers, including children, at least two weeks before boarding.

Starting this week, MGM Resorts International will have mandatory regular testing for unvaccinated employees. If tested on-site, workers will have to pay a $15 copay fee and those who choose to get tested elsewhere are required to provide a result from a PCR test. Those who aren’t vaccinated are notified when they will be tested and won’t be paid for their time off during a required quarantine period if they test positive.

Media
The Washington Post said Tuesday it would mandate the shots for employees as well as visitors to its offices. “Our plan is to require all Washington Post employees to demonstrate proof of full Covid-19 vaccination as a condition of employment beginning with our September 13 office return,” CEO Fred Ryan wrote in a note to employees.
