Executive Order 14042 Requirements for COVID-19 Vaccination of Federal Contractors [Updated December 13, 2021] [open pdf - 724KB]
From the Document: "On September 9, 2021, President Joseph R. Biden, Jr., issued Executive Order (E.O.) 14042 [hyperlink] requiring parties contracting with the federal government to provide adequate COVID-19 [coronavirus disease 2019] safeguards for their workers. Federal contracts and contract-like instruments (jointly 'contracts') must now include a clause compelling most contractors and subcontractors (at any level) to comply with prescribed COVID-19 workplace safety requirements for the duration of contracted work. Such requirements include a mandate for certain federal contractor employees to be vaccinated against COVID-19 by January 18, 2022 [hyperlink], allowing for exceptions only as required by law. This requirement is distinguishable from similar efforts, such as the proposed Department of Labor (DOL) Occupational Safety and Health Administration (OSHA) COVID-19 vaccination rule [hyperlink] that would apply to employers with 100 or more employees--see also CRS Legal Sidebar LSB10662, 'Federal COVID-19 Vaccination Mandates and Related Litigation: An Overview', by Wen W. Shen, for a summary of these efforts. Legal challenges have paused enforcement of the mandate while litigation is ongoing."
