We don't discuss the code of ethics, only once has professional ethics been brought up and that was when my T mentioned that it was unethical to have a relationship with a client, which was kind of a 'duh' moment. I think it is hiding a bit to bring the code of ethics into something. For example, by bringing up the code of ethics they don't need to say how they feel about it, whether for example they want to go to your party but cant, or just don't want to go. If a T thinks it's unethical or wrong I think it would be more beneficial to just say that vs. or in addition to citing a code of ethics I think.
