As a frog, and a nurse, I certainly knew, at least I didn't have to get fired in order to have a clear conscience. I had already taken some time off to help family members in need, and had every intention of going back to work. Then the C19 shitstorm began, and no way would I be part of it. After about two years I was getting texts and phone calls for nursing jobs, still getting them. Sign on bonuses, generous benefits, etc.,. but no way I'm going back now. They're even willing to take me, unvaxxed, but nope.
