Sorry I disagree. See I work in Paris. Where the populace regularly work 35-45 hours and then take month long holidays. My contract allows a minimum of 35 hours/week. Anything after that is voluntary. I normally work the typical 8x5 week. When I decide to do 7x5 I strip out all the extra bullshit and focus on getting out the office. No breaks, meetings, phone calls, etc. my colleagues in he US don't care and don't know. I've worked a full day just like them, but an hour less.
