The Department of Labor's Occupational Health and Safety Administration (OSHA) has released its emergency temporary standards (ETS) for Covid-19 vaccinations within employers with 100 or more workers. Covered employers must establish, implement, and enforce a mandatory Covid-19 vaccine policy or a policy that gives employees the choice between being vaccinated, on the one hand, and undergoing regular testing and wearing a mask at work, on the other.

The standard, driven by an executive order signed in September, will go into effect immediately after being published in the Federal Register, according to OSHA. Employers will have 30 days following publication to comply with most requirements. Testing requirements must be met within 60 days of publication. The Federal Register expects the rule to publish tomorrow—on November 5, 2021.
