Mate, I got your PM but couldn't reply 'cos yer inbox is full! So here's what I was gonna say:
No probs mate, hope it all goes well. But like Charlie Clean said, you could always call them first and set the question hypothetically. I would hate for you to take my word and then get saddled with some bastard key worker with a chip on his/her shoulder, especially when your mrs doesn't know anything - you've got too much to lose. Take it slow and careful, and ask around. If you know other heads that are with the same clinic, ask what they think first. However, I know for a fact that they are under near enough the same confidentiality agreement as doctors, so unless they have a bloody good reason to get the SS involved, then they won't. When my mrs's sister got the job at our drug clinic, she was told in no uncertain terms that everything she sees and hears in the clinic, stays within the clinic. It's a sackable offence to discuss any clients or their activities with a third party. Also, when my first child was born, I had the same reservations as you, so I brought it up at a meeting. They assured me that as long as they have no grounds for concern then there is no need to worry. Good luck man,
FUBAR
