In Canada, most Civil Servant jobs, especially in sensitive records, must be bonded, and and a CPIC check is a requirement.
B, that's horrible that such sensitive, confidential information got leaked out. Anyone who does that would be dismissed. I know of some cases where this has happened, but not with JW's.
Quite a few years ago, the Society wrote a specific letter to Dr's that were members of JW's, and it addressed their confidentiality arrangements. It was quite some time ago, but, I do remember what was commented on the matter.
I know that the Soc expects you to approach your brother or sister if you witness something wrong and if they don't approach the Elders you are to go to that step.
If Dr's or Lawyer's have that patient confidentiality agreement through the exercise of their office, others who are custodials of such information in the care of their positions have a responsibility to maintain the public's trust. When it becomes a matter of concience and the employee can't handle this condition of their employment, they should quit and work somewhere else.
