I have to conduct Adverse DBS Investigations for new applicants when a DBS shows that they have a conviction, normally this involves a chat and taking notes and copies of the DBS, this is sent to Safeguarding for a decision based on my report. Nothing is held on record for longer than necessary and everything gets destroyed at the conclusion.
I normally hold these conversations at a site that has an office that I can use, for confidentiality. I now have one with an applicant at a site where there is nowhere suitable to have a confidential conversation. I've spoken to one of my managers and they said it can be undertaken anywhere, even a public library. I disagree because of the risk and there is every likelihood that we will be overheard, for example, in some rooms, my voice seems to carry even when I talk quietly, I don't want the confidential and sensitive conversation ending up being discussed on Twitter with the hashtag #librarycrimes
