On that note I don't see anyone left wearing surgical or latex gloves outside now (Western Europe).
They use soap and water? Handwipes?
That must be killing any skin they have left. Gloves make so much sense for them. They make sense for everyone.
Gloves are scientifically proven not to work unless you replace them after every transaction, additionally most people do not know how to properly remove surgical gloves without contamination.
Taking off gloves shouldn't be an issue. I would think after a 4 hour shift you would take them off and wash hands because they would be sweaty anyhow and you would smell of rubber.
Unfortunately, they haven't been studied much, and I've seen a couple reports that face shields alone are not enough and they are best combined with masks.
Still, a face shield alone would probably be better than nothing.
Alone, face shields do little to nothing to protect people from the wearer.
