I am gen Y and I freely admit that I do more work in a 'designated working environment'. I hate monotonous work, and it has led me to building scripts etc to do the boring work for me. Our strength comes from that desire to not be bored, so we come up with creative solutions to bypass them. If a company can't bend to that mentality, and we aren't completely financially stuck with having to work, we will quit for a place that does.
