My wife was recently given a verbal warning by one of the managers in her company. She's not too worried about that in itself because she's not long off retirement, but it turns out the guy has told other people in the company about it, people with no requirement to know about this, who are subordinate to her, and to whom he had no business tattling. Is the company legally obliged to keep this kind of thing confidential, and if so, is it liable for any breach?
