Liz Jones is off her rocker.
I agree with what most people have said here. It's about the work-life balance here in NL.
I'm a teacher and in the UK there would be no way, without children, that my school would support me working part-time. In my whole (secondary) school there were perhaps 2 or 3 part-time teachers, all with young kids. Here it's accepted as notmal that not everyone wants to work 5 days a week. At least 40% of the teachers in my school here in NL work part-time.
No one makes you feel guilty for not being in 5 days a week. My friends in the UK tease me about being a part-timer (I teach 4 days a week) but I know that I'm a more efficent teacher because I have that little bit more time for myself. I used to be ill quite frequently when teaching in the UK with colds and bugs, but here it just doesn't happen.
And, it's not just the ladies. Two of the male teachers in my department work only 3 days a week.
I don't know any SAHMs here.
