Here in the UK there's a really noticeable difference between London and the rest of the country. In London it is considered normal to stay at work late until 6pm/7pm or later. In the rest of the UK it's considered normal to leave at 5pm/5:30pm.
I hear talk of 70+ hour weeks in the US for tech workers in the US. That isn't too much of a thing here in the UK. Especially outside of London.
