Gloves only help if you don't touch your face when wearing them. If you're not used to avoiding touching your face (I had it drummed out of me when working in catering but have slipped in the 20+ years since then) then it doesn't matter whether you do it with a gloved hand or not. You might be more aware of touching your face if you're wearing gloves but it doesn't stop you from doing it.
Wearing gloves gives no more protection than washing your hands properly whenever you'd change the gloves.
The transmission isn't into your hands, it's from your hands and onto your face and into your body through mouth, nose or eyes. Wearing gloves doesn't do anything to prevent this.
If you pick up a dog shit using a gloved hand and then touch your face your hand may be clean but you've still got traces of dog shit on your face.
Our admin staff (with laptops) are doing this Weds/Thurs, but I feel sorry for our branch staff who have no choice but to face handling large quantities of cash from the mostly elderly (building society) customer base that use branches...
