And how would you know that an employer refused you a position because of your health record ?

These kinds of laws exists in most country, but if you cannot prove it, they are useless. So if a employer has a public access to your health record, what you prevent him from doing the above and tell you a random reason ?

There was a case in France were an Ikea director has access to private police record and was making hiring decision based on that. It's completely illegal but they did it for years before getting caught.
