One Rule for New Starts, and Another for Others?

I have been taking part in a few interviews on placement and it has been commented a few times that i should remember to go over confidentiality with the client at the beginning of the interview. However, not one interaction i have seen so far involving a member of the employed team have yet to do this!
Now i know I'm not covering it either (as i keep forgetting!!) but the fact that i am am almost getting into trouble for something that doesn't seem to be getting covered anyway seems odd to me. Is it because the employed staff are so eager to be authoritative to a student or is it that they themselves have become oblivious to how they conduct their own interviews, almost assuming that they are doing everything right, when in actual fact they are not doing as they preach!!
I was thinking today that too many professionals now get away without reflecting or evaluating on their own practice, it seems to fall by the way side after a professionals 'probation' year on a job. Does this suggest that no one needs help or guidance in their ob after that, are all people who have been in a job after their probation year experts needing no help or advice on how they are conducting themselves in their job?....personally i think not!
Another clear example comes to mind of teachers who have been in the same post for 20 years, they are seen as experts in their field and on paper that may be so but are they actually up to speed on how to keep a class in the spirit of learning or has it all become routine and dull for them?
I'm starting to think that maybe professionals should be critiqued by the new 'probation' students surely they are the new starts coming to it with a fresh head on their shoulder, eager and willing- maybe they shouldn't be seen as a threat as they so often are.
