How are these things the same?
Either way, PTO that allows workers to take enough time off to clear a quarantine order isn't unreasonable. All this chit-chat about all the workers staying home and grocers shutting down is missing the forest for the tress.
also PTO is usually subject to approval, not just choosing to stay home whenever.
It doesn't seem unreasonable to me for an employee to be able to call in and say "Hey, [I have | my kid has] [condition], I need some time off" (and get that time off without fearing for their job, house, and food supply).
I'd love for everybody to get 3 (or more) weeks of vacation and 2 weeks of sick leave. But, the chances of American employers jumping from literally nothing (in many cases) to anything resembling a reasonable policy is next to zero. Because stock market. Or profits. Or reasons.
