American Postal Workers Union Statement on Mandatory Vaccination for Federal Employees:

Various media outlets have reported that the White House is considering mandatory COVID-19 vaccination as a condition of employment for federal employees. Maintaining the health and safety of our members is of paramount importance. While the APWU leadership continues to encourage postal workers to voluntarily get vaccinated, it is not the role of the federal government to mandate vaccinations for the employees we represent. Issues related to vaccinations and testing for COVID-19 in the workplace must be negotiated with the APWU. At this time the APWU opposes the mandating of COVID-19 vaccinations in relation to U.S. postal workers.
