The best science indicates asymptomatic spread accounts for 0.7% of the spread. Even if masks worked, isn’t that emphasized the most unlikely form of spread?
How about, “Stay home if you feel slightly sick”. And let everyone else work.
One of the long term learnings/lifestyle changes that should come out of COVID is to stop incentivizing working and going to school when sick.
NO MORE “perfect attendance awards”
NO MORE combined PTO.
NO MORE dinging evaluations for using sick days.
