Shutting their business down will do far more than a lawyer can hope.

Corporations are situated in such a way that NO PERSON is liable, the Corporation is (it is considered a person in court) They have insurance for such things. You are just encouraging the bureaucracy and that serves to make them all money. If one were able to get a lawsuit through it wouldn't affect anyone in the corporation, they will be allowed to offer a waiver that will essentially be a gag order, enforceable because you will consent. It is how these class actions work. If you sign on to one then you accept the outcome of the whole and forfeit your right to sue individually. If they do not win, do not collect more money than it costs them to pursue or settle out of court then all of that will be for nothing. I have been in a couple. The companies get a slap on the wrist and it is business as usual.

Did you know that walmart was found guilty of cutting employees hours? Before the end of the week they would go to your time card and shave a few minutes off here and there. They got caught and had to settle out of court. Few signed on because they were afraid of clap back from walmart later. I got a nice chuck of cash for the time they took from me ($700 for .38 hours) but NO ONE GOT IN TROUBLE!!! Walmart kept doing as they do and getting worse by the day. The settlement that I entered into has that gag order on me, I am not supposed to talk about it and I am not allowed to go after Walmart for anything.

Meanwhile, you can show them what is up by refusing to work for someone that would attempt this. It isn't going to be easy or fast, but it is literally the only way to get at them at this point.

It is in no way saying anything of the sort of what you suggest, if anything it allows you to get out before they try to mandate that they have access to your medical records anyway.
