Try and get here at 8:30 and work till 5, but we can pretty much turn up when we need to - in time for our first meeting of the day. As long as our projects are finished by completion date, we can do what we like. What usually happens though is that I slack around at the start, then have to work14 hour days to catch up!
We do a 37.5 hour week, I thought everyone did only this many hours these days, but it looks like a few also do a 40 hour week...
