This article is distressing. In my opinion, the NHS has no right to discipline its employees for discussing anything with patients. The patients are the true employers. The NHS is merely a monopolistic state agency between them and their medical carers. If a patient didn't want to talk about religion and asked a carer to stop, that's another issue. Asking for the "right" to talk faith (or talk about anything else) implies that the state has the right to dictate the content of private conversations. It doesn't.
