I've been reading along, was considering my response when JPB and ehBeth made good posts.
I thought JPB's post about "expectations" was especially good.
I have a few different perspectives on this. One is as an employer, one is as someone who did job training, and one is as a mom.
As the first two, my advice is basically OMG woman be careful!
Really dangerous territory, especially if you're seen as the ringleader. The vice president being involved might be good, I can't quite tell. What is the general response so far?
From that perspective (really all I guess), I think the decision to go back to work should include the cost of childcare. If the salary does not adequately cover the cost of child care, don't take the job.
Now, big-picture wise, I think there should be more allowance for parents to both work and have children. (All parents, not just moms.) It's too difficult right now to find a balance. Other countries do, it can be done. But right now if a woman (especially but not only) is in a demanding career, her choices are still pretty stark. She can have a child -- and not see him or her that much as she puts in the hours required of the childless. She can have a child and take a break from work -- and severely impact her chances of progressing along her career path. She can wait to have a child until she's reached the pinnacle of her profession -- and maybe no longer be fertile. Or she can just not have a child at all (hopefully because she never wanted to in the first place, not because her choices were between having a child or advancing in her career).
Then there are all kinds of other permutations of the difficulties of balancing work and parenting.
I do think that American companies need to improve this situation.
If your company is willing to work on this, good for them. But it has to be sensitive to people who don't have children, and I do think you need to be very clear to the company that you have no particular expectations, just exploring possibilities, and if nothing works out, oh well, you'll deal.
