windy, just seen your post of 15:31 to me.
What's selfish? Well, your attitude is. If you think it is morally 'reprehensible' for a woman not to announce her pregnancy/hope of a pregnancy - which is what we're talking about - you're making a moral judgement.
You do not get to throw your hands up in horror when someone else expects some moral decency from you.
You chose to get involved in running a small business.
That may have been a very sensible choice. But it was a choice.
I never said the problems were the same for a bigger business - I said you don't seem to care about bigger businesses, only about yourself. Which I think is selfish. It does rather indicate that your argument is not a passionate economic one - it's a self-centred one. If it weren't, you'd object to all the economic downsides of hiring women of childbearing age, not just the ones that affect you.
And I would still like to know what you think women in my situation should do? How 'economically responsible' is it for me to say I won't bother earning then?
