That covers you but what about the members of staff who actually have a genuine reason for not receiving the vaccine? Peter in ops recently received a double lung transplant and no longer has a functioning immune system. Are you prepared to also sign an agreement barring yourself from ever walking into one of our offices or attending social gatherings?

If Peter in ops has no immune system, he will get sick from non-COVID viruses or diseases regardless of what is done by other people. In that hypothetical situation it would be him who shouldn't go to an office, not other people.

I'm not sure why you immediately assume this is hypothetical. I know a couple people in similar situations. They exist and are not so uncommon as to assume the OP is making it up.

It's also not the doom scenario you describe. Yes they have to take extra precautions, and yes the people around then have to make a point to not be around when they are sick, but with a little consideration plenty of people with highly compromised immune systems live meaningful lives.

People with compromised immune systems need the shot even more
