In higher ed we are experiencing a huge exodus of administrative assistants (what used to be called secretaries). It isn't due to vaccine mandates, though we have them. I think we did lose one person to that policy. For most it is due to the fact that they discovered that they can work remotely, at home, very effectively. Yet their employer is now asking them to return, in person. Other employers, however, are reaching out to them and giving them the opportunity to work remotely, often at a higher salary.
