President Joe Biden announced a new rule Thursday that could impact 80 million U.S. private-sector employees, mandating that all employers with more than 100 workers must require vaccination or weekly COVID-19 tests. What does this mean for commercial landlords?

It's an especially notable development for Florida, according to Miami attorney Jeff Gilbert of Saul Ewing Arnstein, who noted Gov. Ron DeSantis has fought past mandates despite high infection rates.

"I think there will be butting heads with the governor based upon the executive orders that he's issued previously, including the executive order 2181, which he issued in April, that prohibited businesses from requiring that any patrons or customers provide documentation that they are vaccinated," said Gilbert. "It may be that the governor may try to issue additional mandates or have the state file additional lawsuits in response to the president's mandate."
