Well, that depends. 40 hours a week out of 168 is less than 1/4, but it's certainly true that you spend at least half of your weekday, waking life at work. But more pertinently, it should be time that's set aside for work. I don't know why what we do outside of work should even be a factor, or why I should have to share the cultural values of my coworkers. It comes dangerously close to discrimination.
