1. Men don't work part time in law firms. I've seen it once in 15 years of working in major law firms.
2. It was assumed I would lose interest in my job before I even went on maternity leave. No one ever asked me. I worked until 40 weeks and never had a day off during pregnancy.
3. We moved in part because I got sick of beating my head against a ceiling I didn't build. If my career had been as it was supposed to be it wouldn't have even been on the radar.
I think you really don't understand what the word choice means.
Sorry I'm a bit passionate about this because it doesn't have to be this way. DH is a partner in an international law firm that actually knows how to treat and progress part time women. He mainly employs women and most are part time. He's learned from my experience.
