Starbucks told its employees in a memo on Tuesday that they would no longer be required to be fully vaccinated or submit to weekly coronavirus testing. Just two weeks earlier, the company had detailed the requirement and set a deadline of Feb. 9.

The Supreme Court’s decision did not prohibit companies from keeping their vaccine rules in place, and many will continue rolling out stringent Covid-19 safety protocols, especially as Covid case counts remain high.

Starbucks’s move to drop its vaccine-or-test deadline highlights how the court’s ruling has put the responsibility for determining vaccination rules squarely on employers. And companies face a patchwork of federal, state and local laws, which range from vaccine mandates that are stricter than the federal government’s to laws blocking companies from requiring workers to wear masks.
