This "working from home" trend seems to be gaining in popularity the last years, at least here in the Netherlands.
I never had anyone ask about this arrangement before though. Maybe because you mostly see it in the non-commercial sectors, not sure.
Anyway, the first thing that comes to (everyone's?) mind is that working for home is just a way to slack off. Especially if it's on friday.
I am also not to keen on having people work away from their collegae's, which seems counter productive.
What is your view on working from home?
