Confidentiality

As most of you know and for those that don't, I am currently training to become a counselor/therapist.

A big topic on this course is confidentiality.

Before I write about what I have learnt so far, I would like to ask you a few questions about this subject.

1.If you were going to counselling does the issue of confidentiality concern you?

2.Would it matter to you if this counselling was arranged through your place of work, would that sway your level of concern either way?

3. Do you wonder about the notes your counselor has or would make?

4. Do you know what would cause a counsellor/therapist to break confidentiality?

Thanks for reading this and any contribution you care to make. Any questions feel free to ask me and I will try to answer them.
Why do I want to know this? Well I will be going out and working with clients in the very near future and anything that will help me put someone at ease the first time they step through that door would be invaluable to me. If anyone has a had a horrible experience with a counselor/therapist I hope to learn something from that mistake and not through too many of my own.

UPDATE:
I really appreciate you taking the time to answer my questions and I am working on the rest of the post :)
