when I started my current job, I was just working normal office hours, but for the first 6 months until I passed my probationary period, i was working at Borehamwood- a good 2 1/2 hour drive from home- each way, I would leave home at 5.30am, and get back home around 7.30-8pm (depending upon traffic) eat then go to bed to start the whole round again next day. after my 6 month probation I was allowed to work from our office at Childerditch, a whole hour closer to home, where I have worked since, its still a 12 1/2 hour day (leaving at 6am returning home at 6.30pm) but that is due to optimising my timings for traffic and generally starting an hour early every day, this gives me some leeway when traffic is bad, or when I need to leave early.
