I am keen to have a cleaner again, my pre-pandemic cleaner is refusing to have the covid vaccine (I know this because we are friends on Facebook and she's constantly posting conspiracy theories.) I felt it would be more respectful to just discreetly get a new cleaner than tell her I'll only ask her back if she gets vaccinated. However how do I tell an agency that I'd only like a vaccinated cleaner? Are they even allowed to ask, so should I?
