On September 24, 2021, the White House's Safer Federal Workforce Task Force released new guidance on COVID-19 workplace safety protocols for federal contractors and subcontractors. The guidance accords with President Joe Biden's September 9 Executive Order, which applies to most (but not all) federal contractors and subcontractors with new contracts, new solicitations, and extensions or renewals of existing contracts entered into on or after October 15 for the provision of services, construction, concessions, and work on federal lands for executive branch agencies (for more info on Biden's Executive Order, see "President Biden announces COVID-19 vaccine mandates for certain employers" on page 4 and "Questions employers are asking about Biden plan to vaccinate the unvaccinated" on page 6).
