I would like to give some benefit of the doubt with regard to intent since the memo itself doesn't specifically say they can't talk to patients in their own language, and I can imagine scenarios where a staff member doesn't know what is happening because discussions are happening in a language they don't speak.
But... holy shit, how could you write a memo like this and not expect to end up in the media? It's like the person writing it can't imagine a world where English isn't the best language for all circumstances.
I feel like there is potentially a problem but management lacks the problem solving skills to come up with a real solution.
