And that is the way it should be. Unless you're working in a sweat-shop type setting where it's really easy to count how many shoes you've made during the day, then your employer is paying for your time. Time might be money for a company, but for me, my time is my life. I'd sure as hell prefer to spend my time doing something besides work, but I'm perfectly willing to trade some of it for some money. If my employer doesn't want to pay me to boot my computer, that's their problem, not mine. Asking me to give away my most precious asset (my time) is simply not a realistic idea in today's world. The days when that sort of sacrifice and loyalty were reciprocated are long gone.
It reminds me of my father's workplace, a will-remain-nameless power generating facility, where some new manager thought it'd be a good idea to cut the janitorial staff. The engineers and electricians (and management) would be responsible for keeping their own areas clean. It might seem reasonable to some people, but they were then paying high wages to their engineers and management to do janitorial work. I believe it changed when the director at the station remarked to his secretary, "I noticed my garbage hasn't been taken out for the past week, who's responsible for that?" to which she replied "You are."
