Hi, thanks for the replies. I am thinking of work life balance really. My old boss has adult children, my DS is primary.
Is there a 6 day week, long hour culture in offices? For example I was offered a job in Istanbul, fabulous package but the minimum office hours were 8am-7pm!
Seemed industry wide. People didn't seem to work smart they worked long. Let's sit drinking tea for four hours over something my UK peers would've done in 30 minutes! UK employees were coming up to me in breaks and telling me not to do it!
Coupled with the commute I would have been travelling and working for around 15 hours a day due to location of schools.
It's an international company so at least the holidays are UK reflective. Schooling is paid for but that doesn't worry me. Culture and heat etc - we have family &friends we visit in Egypt and Dubai, so it wouldn't be a shock, and DH served out there. But I can't help thinking it's the grubby sanded, less interesting cousin of UAE. Don't know where I got that idea, am I wrong? 
The whole male environment doesn't affect my line of work too much - it's fashion. But my DH is a SAHD, and this might be somewhat of a novelty, I'm not sure. He could go back to work though - but that depends on me!
I just wonder whether I should move the whole family to a short term upheaval (couldn't see us doing it for more than 3-5 years) when we love where we live, but don't have time to enjoy it.
It's difficult to come back here and we are almost reaching the time for a more stable permit.
Sometimes I feel like telling DH to go back to the rat race so I can put my feet up!
