As a U.S. government contractor, Ursa Major is subject to President Biden’s September 9, 2021 Executive Order on Ensuring Adequate COVID Safety Protocols for Federal Contractors requiring federal contractors to be fully vaccinated from COVID-19. However, recently a federal judge in Georgia issued a nationwide preliminary injunction that prohibits the government from enforcing the federal contractor vaccine mandate. The order covers all contractors and subcontractors in the United States and its territories, and will be in place until further notice. Additionally, while Ursa Major is still subject to OSHA’s Emergency Temporary Standard given our 100+ employees, its implementation and enforcement is currently suspended pending future developments in the litigation.
Given these updates, we are suspending the Mandatory COVID-19 Vaccination Policy until further notice. With this is mind, Ursa Major fully intends to comply immediately with changes to any COVID-19 mandates.
