Supreme Court Stays OSHA’s Vaccine-or-Test Mandate for Employers with 100+ Employees

In the fall of 2021, the Occupational Safety and Health Association (OSHA) implemented regulations that would require nearly all employees of private employers with 100 or more employees to be either vaccinated against COVID-19 or subject to weekly testing for the virus. The regulations were challenged by a number of states and industry groups, which resulted in a stay, or a hold, being placed on the regulations by various U.S. Circuit Courts of Appeal. See our earlier Legal Alert on the topic. Thereafter, the appeals were consolidated and the Sixth Circuit Court of Appeals lifted the stay.

Yesterday, in two separate cases, the Supreme Court reimposed the stay of the OSHA regulations but also lifted a stay that applied to a separate vaccination mandate for certain employees in the health care industry. The Court’s ruling effectively puts the OSHA requirements on hold for the foreseeable future and most likely permanently.

While the Court’s OSHA decision limits the federal government’s ability to mandate vaccines and routine testing in the workplace, at least for now, some jurisdictions, including New York City, have implemented their own vaccine and/or testing requirements that remain in effect.

What Does This Mean for Employers?

While for now the federal government has been limited in its ability to mandate COVID vaccines and testing, at least outside of the health care industry, employers can still choose to implement their own safety protocols in their workplace, which can include routine testing or vaccination requirements. Employers will need to ensure that they are following the regulations in the jurisdictions in which they do business.
