Can a supervisor (or can other employees) ask for the vaccination status of an employee?

Anyone is free to voluntarily share their vaccination status with others, but employees should refrain from asking their peers whether they are vaccinated. Supervisors, however, are permitted to ask their direct reports about their vaccination status. Supervisors should not disclose this information to others and should not ask questions specific to reasons for receiving or not receiving the vaccine. In addition, supervisors should not take proof of vaccination, rather employees are encouraged to confirm their vaccination status via Salesforce Health Cloud. If supervisors or employees should have any questions, they should contact their unit HR. Technical services employees and other employees represented by a collective bargaining agreement should check with their unit HR to determine if there are other requirements applicable to them.
