I have had 90% of my teaching career in the independent sector, and I love it. For me it is work hard:play hard.
I am currently in a boarding prep (no boarding duties). I work until 6pm 4 days a week, with Saturday and Wednesday as half days.
I have the same teaching load as at any other school, but because the day is stretched, I get all my prep and marking done in school. I never, ever take work home.
There is no burgundy book in the independent sector, so there are lots of duties and cover obligations (although there's not that much cover as staff don't get sick as much). I have 4 hours of duty a week, which seems like a lot, but an hour of that is a couple of afternoon teas, which is a lovely time to socialise with the boys.
What I love about my school is that the whole experience is very holistic. I am a Science teacher, but I am not stuck in the lab. I get to take Chapel, run non-science activities, and am part of an excellent pastoral team. I draw the line at Games, but am too old and the wrong sex for that.
The parents can be pushy but, seriously, I have only two or three that want to see me every so often, and it is always very polite. I feel that I am given enough time and support to jump through the parent hoop.
