I work with 2 people who are involved in an ongoing investigation into bullying. A customer came into work today and asked me about the investigation as the ‘victim’ had told him about the ‘bully’ and named her and given details of what she alleges is the bullying. I have reported the conversation to my line manager but they do not seem to have done anything about it so should I tell the ‘bully’ as surely she has a right to know what is being said about her as I would have thought both people should have been told about confidentiality?
