My company operates a standard week of 35 hours, but we get flexi time so I might work a bit longer one week, then have a couple of long lunches or early finishes the next week. I tend to average around 37 hours as I can have a day off each month if I build up enough flexi time (ie. 7 hours). :) I'm not sure how long I'd say an optimal work week would be, any amount of time spent at work is time that I could be using to do something else, but I kind of need to get paid! :sigh:
