Supreme Court stays OSHA vaccine-or-test mandate (NFIB v. OSHA)

In a 6-3 per curiam decision, the Supreme Court stayed the OSHA emergency temporary standard requiring vaccination or weekly testing for ~84 million workers at employers with 100+ employees, holding OSHA is empowered to set workplace safety standards, 'not broad public health measures'; the same day the Court allowed the CMS healthcare-worker mandate 5-4 (Biden v. Missouri). The dissent argued OSHA acted within its core mission against a 'grave danger' in workplaces and that the mandate contained a testing alternative.
