The coronavirus shot has been administered in the United States under an emergency authorization from Food and Drug Administration for the past eight months. Some union members and workers opposed the vaccination, and some employers were reluctant or unable to order it. This was because the vaccine had not yet received FDA full approval. This was Monday.

Devjani Mishra is a New York-based attorney at Littler Mendelson. She specializes in workplace issues. Her prediction was shared by others from the business, law, and health worlds. More companies will require vaccines for their employees.

Soon after the FDA took action, Walt Disney World reached an agreement with its unions to mandate that all employees at its Orlando theme park, Florida, be vaccinated.

CVS, a drugstore chain, said that employees who come in contact with customers will need to be inoculated. Chevron Corp., an oil giant, said that some of its employees will need to be inoculated. This includes those who live overseas, travel internationally or work on offshore platforms in the Gulf of Mexico.

Ora Hirsch Pescovitz is the president of Oakland University, Rochester, Michigan. She said that she pushed “go” when the FDA made this decision. The university announced Monday that 800 faculty members, 1,500 employees, and 18,000 students would have to get vaccinated. Prior to that, students who lived on campus were the only ones required to be vaccinated.

She stated that the university could have legally mandated vaccinations prior to the FDA decision, but she waited because Pescovitz (a pediatrician) believes that the authorization would be persuasive for those who are still on the fence.

Health experts expressed optimism Monday that the FDA’s actions would increase the U.S. vaccine rate. This was down from an average of 3.4million shots per day in April.

Due to growing concern over the highly contagious Delta variant, where many people have died, cases, and been admitted, the number of shots has risen to 850,000 per day. This has wiped out months of progress.

Littler Mendelson released Monday’s survey showing that 9 percent of employers have already mandated vaccines for their employees. Another 12% plan to do so in the near future. Only 1% of the firms Littler Mendelson surveyed had made vaccine requirements in January.

Employers face a risk at a time where many are struggling to fill open positions and workers are confident about finding better jobs. An employee may “say OK, fine” when faced with a vaccine requirement. Mishra stated, “I’m leaving.” “It is not a given that you will be able fill that job by someone who has been vaccinated.

Ali Mokdad, an associate professor of health metrics sciences at University of Washington, Seattle, stated that he does not foresee any significant backlash.

“People will realize that mandates are a way for them to open up their businesses and make their wages more affordable. He said that they would see the benefits and will be happy to accept them.

President Joe Biden made an announcement earlier this summer that all federal employees will need to be vaccinated. Federal workers could also face weekly testing or other measures.

Two of the nation’s largest private employers aren’t showing any signs of slowing down. Walmart stated Tuesday that it has not changed its policy which mandates vaccinations for store workers, but not for office workers. Amazon, which does not require vaccinations for its employees, didn’t respond to a request.

The auto industry has not required the vaccine. Ford Motor Co. and General Motors have both stated that they don’t require it. CEO Mary Barra however, has not denied the possibility.

Ladders Inc., a career-advice website, released last week a study showing that there has been a 50-fold increase in job openings requiring applicants to have vaccinated since January.

Laurie Monteforte, a spokeswoman for Ladders, predicted that vaccine requirements would only increase after the FDA’s decision. She said that many employers have exhausted all vaccine incentives, such as bonuses and other perks.

Employers who require vaccinations are legal. Employers, whether private or government, can usually require that workers be immunized as a condition for working. However they must provide exemptions or accommodation in certain cases.
