In health and social care, as a practicioner you're usually required to not disclose any information about your client openly to other people.
The only exemption here is when doing an super- or intervision with your peers, here you can "breach" this confidentiality with obviously still presenting this person as an anonymous case.
Another exemption is when you're given information that revolves around possible hurting other people or self-hurting coming from the client itself.
