Both of these positions on the subject are needlessly binary. I often find it the case that, even though I erect careful boundaries between work and non-work, when I leave a problem on my desk, I will continue to ruminate about a solution throughout the weekend, say. Similarly, I will Strategically avoid email when I'm recharging. I don't think it's so easy to boil down as black and white.
