I run a small consultancy and Development Friday's are almost mandatory for my developers. Everyone is given Friday afternoon to learn new skills or improve existing ones, I even tell my clients that this happens (we charge by the week) and in the last 4 years I've only had one complaint and we quickly cancelled the contract with them after.
