Remote work is not going to go away anytime soon, and CEOs are concerned.

With the rise of the Delta variant and the recent surge in Covid-19 cases, many large companies are postponing their return to the office until early next year, according to a report in the Wall Street Journal. That timeframe would be nearly two years to work remotely – and many company executives are concerned about how this could affect their business.

Amazon and Facebook recently announced that they would postpone their return to office work until early next year. Apple announced its employees that they would not return to headquarters until January 2022. Lyft plans to bring employees back in February, which would mean 23 months of remote work.

“If you have a small rash, people go back to the old way. Well, it’s not a rash,” Pat Gelsinger, CEO of Intel, told the Journal. Hence, Gelsinger believes remote work won’t go away even if Covid fades. “There’s no going back.”

Prudential Financial vice chairman Rob Falzon told the Journal his biggest concern right now is retaining talent. “When individuals culturally distance themselves from their organizations,” he said, “it becomes easier and easier for them to make decisions, to leave and go elsewhere.”

Surveys show that American workers enjoy working remotely. A survey by background check company GoodHire last month found that 85 percent of respondents prefer to apply for jobs that offer full or hybrid remote working options. Almost a third said they wouldn’t even think of applying for a job that required them to be in the office five days a week.

As a result, employees at some companies have pushed themselves back when asked to return to the office. Apple employees have sent two petitions to corporate management in the past few weeks protesting the tech giant’s now-abandoned plan to return to the office in September and asking for more flexible options.

The trend towards remote working can create difficult conditions for small businesses. As Inc. wrote earlier this year, performance requirements vary from state to state, which can be a headache for companies with small or nonexistent HR departments. And tech giants who can hire workers anywhere in the country can make it difficult to hire. To counter this, some experts recommend offering salaries that vary based on employee location – and using websites like PayScale or Glassdoor to make sure those salaries are competitive.
