I suppose, Xenia, that because I got paid maternity leave (up to 6 months) that sort of cast the die for which career would take the backseat. I think I decided that seeing as I had clearly marked my card where my employer was concerned (by having children at all, being pregnant in the first place and having 6 months off), it seemed silly to compromise his career as well, leaving us with no main career.
And once that trend was set, it has been perpetuated.
An interesting question for mothers is - would you go back to work full time if you knew that the children were being cared for by their dad?
And I have to say that I might have considered it. But where would breastfeeding fit in, and physical recovery from pregnancy (which I did take almost a year to do)?
I honestly believed that the dice were so stacked against women in the workplace that there is little point trying to make it the main career once you have children. If employers were not so terrified of the fertility of their female employees, then it would do a lot for the prospects of all women in the workplace.
Where I work is very female dominated (except for the top job which is invariably a man), and the fact is that the women take time off when the children are ill, the women are the ones who go part time, the women are the ones who ask for more flexibility than the men. Until this changes as the norm (which I don't believe it will), men will always be the employee of choice for them, given a free hand.
