Yep - my (somewhat dull and conservative) employer did this as well. I was cynical, but year later I'm pleasantly surprised to be proven wrong - I think we collectively all took 15% more holiday. Not a mind-boggling change, but not the "we'll all be bullied to stay at our desks" result I'd anticipated. Anecdotally I think the largest change is people get less precious over guarding their holiday as a precious resource, even if they've no idea how they'll spend it. You finish your week's work on Friday morning? Ask if anybody needs anything from you and then just take the rest of the day off. No compulsion to find some busy-work and protect 4 hours of vacation.
