Nancy Rothbard, chair of the Management Department at the University of Pennsylvania's Wharton School, joined "Squawk Box" on Thursday to discuss the dilemma employers are facing when it comes to deciding whether to require their workers to get the coronavirus vaccine.

While some companies, including JPMorgan Chase, Salesforce and PricewaterhouseCoopers, are dumping office space, others are ramping up their return-to-work plans. Just this week, Google, one of the first major U.S. companies to send employees home last year because of the coronavirus, told staffers it is accelerating plans to get back in the office ahead of the Sept. 1 return deadline. In a memo to Bloomberg employees first reported by Business Insider, Michael Bloomberg said he expects workers to return to the office as soon as they are vaccinated. In a survey of more than 350 CEOs and human resources and finance leaders, 70% said they plan to have employees back in the office by the fall of this year, according to a report by staffing firm LaSalle Network. “I think every office will have re-entry done by Labor Day,” said LaSalle Network’s founder and CEO, Tom Gimbel. One year into the coronavirus pandemic, employers, particularly tech companies like Microsoft, Twitter, Square, Spotify, Shopify and Amazon, extended work-from-home policies, some indefinitely. That helped perpetuate the idea that remote work was here to stay. “Everybody was driven by the tech companies,” Gimbel said. “Then, all of a sudden, you get this ‘vaccines for all’ laid in your lap.” (In fact, many states are now expanding eligibility guidelines for who qualifies to get a shot.) “My bet is, within a year, things will retreat back to normal,” said Peter Cappelli, director of the Center for Human Resources at the University of Pennsylvania’s Wharton School. “It’s hard to change workplace behavior.” Of the companies that are now planning for office re-entry, managing employees who want to continue working remotely is a top concern, LaSalle Network found. Vaccinated or not, more than half of employees said that, given the option, they would want to keep working from home even after the Covid crisis subsides, according to a separate survey by the Pew Research Center. Other obstacles included addressing fears about commuting to work and reacclimating to the office environment, as well as potential conflicts between executives and staff over return-to-work policies. Meanwhile, business leaders are also working to make vaccines more accessible to their employees and even incentivizing them to get inoculated. Already, employers such as AT&T, Instacart, Target, Trader Joe’s, Chobani, Petco, Darden Restaurants, McDonald’s and Dollar General are among a growing list of companies giving workers time off and extra money to get vaccinated for Covid-19. » Subscribe to CNBC TV: https://cnb.cx/SubscribeCNBCtelevision » Subscribe to CNBC: https://cnb.cx/SubscribeCNBC » Subscribe to CNBC Classic: https://cnb.cx/SubscribeCNBCclassic Turn to CNBC TV for the latest stock market news and analysis.
