I agree with your first point (back to why I think people should sign in) but please don't disparage healthcare workers to prove that point. It's really hurtful when we have been putting ourselves at risk each day. I trained in a huge inner city with high HIV rates and gun violence etc and I have never felt as much personal health risk as I do right now, so to imply that we are being careless is a slap in the face.
I don't know any of us that are doing what you describe. We have all been coming into work, changing into scrubs, putting on a surgical mask, and changing our shoes. Before we leave, we change back into our normal clothes and put our "street mask" (cloth one) back on and our street shoes back on and leave. And then STILL take our shoes off outside, throw those clothes in the wash, and shower. Those who are not changing at work are heading straight home and stripping in their garages. So, yes, you might see me walking in and out of the hospital in the same clothes, but those clothes are not actually what I wore while working.
I literally haven't hugged my children on entering my house since this started. I won't hug them until I'm out of the shower and changed. That is much harder than I ever imagined possible...please be thoughtful before throwing stones like that.
