@ShamblesRock you don't work in the sector do you? You still haven't explained why you think WFH is relevant.
If you can think logically, you'd realise that people who predominantly WFH don't tend to print much, because they don't have to go anywhere, because they're WFH. If they're in a role where their work is online they're not printing. Also they won't be printing because they don't have access to printers. Because they're WFH.
It's the workers who are working face to face that have to sometimes print documents (for which they'll go to the office) and travel with them. How exactly do you think workers should be shamed into not having their cars broken into when they're at court/on a visit/picking up their kids on the way home etc etc?
Even before any WFH, the vast majority of social work visits are at the end of the working day (because that's when children and families are at home, ie after school). So if a worker has to take some minutes out to a parent, and then have something prepped for a meeting first thing at a school, they'll have some documents in their bag. They're advised to print minimally, keep things out of sight etc, but how exactly do you suggest they avoid getting mugged/getting broken into? No one wants to have their stuff stolen, and to be faced with disciplinary on top of everything else.
You seem to be very keen to blame the victims because you have some chip on your shoulder about home working. In practice home working has made it more secure, not less, because more organisations have finally signed to to systems that allow for electronic sharing (eg secure email and storage) so it's more common that paperwork is only needed for members of the public.
