Yes I used to do regular 9-5 years ago but these days the larger organisations seem to favour flexi time to allow for things like the school run and for those who travel quite a distance to and from work.

Personally I prefer 9-5 than having to start here at 8 but the plus side is I get away early on Fridays (12noon) and I can accrue enough flexi to take one Friday off per month.  Like CG, I can therefore keep my annual leave for other things.

For info when I worked 9-5 (8 hrs) I never got paid for lunch which was usually an hour so only got paid for 35 hours.  In my last company we worked 37.5 hrs per week.  I'm actually working less hours now and getting paid more for it.
