I agree but...
If you need to take the vaccine to keep your job, what will you do?
You're right. They pretty much have people over a barrel, unless people start suing & winning. But that can take a while. I'm no lawyer, but I don't see how it can be legal to force a medical procedure or medicine on people or be forced to reveal confidential medical information.
Some places are offering an alternative of making you wear a mask if not vaccinated. Of course, that's not much of an alternative & then tells the whole world you are an "evil noncomplier".
