Still just playing devil's advocate here but, how could this not be applied to this scenario? Someone with COVID could potentially be harmed themselves or inflict undo harm on other employees. As could someone with a drug or alcohol problem.
Run the numbers. Math is a thing.
"Potentially" is such a subjective word. Any human could potentially rape and murder their co-workers. Potentially they could set fire to the building, killing everyone inside. "Potentially" is a synonym for "possibly". Then a rational human has to consider what is
possible (literally everything), vs. what is
probable (which narrows it down to something one should worry about).
Is it probable that an unvaccinated individual will infect their co-workers and kill them all? Or is it just possible? And if
possible, how possible are we talking? An enormous possibility, teetering on the edge of probable, or just a remote possibility?
Let's do the math!
The data are available and based on CDC numbers roughly 10% of Americans have contracted the covid virus, and .2% have died of it. Note the decimal in front of the 2. And that is since the beginning, March 2020 before there even was a vaccine.
So is it possible or probable that an unvaxxed person will infect their co-workers and kill them all, or any of them?
That's a real question to you.
