There are always sacrifices to be made, even when both of you work.
I work in the medical profession, my husband too. There is a pay scale in place that apparently avoids discrimination based upon specialty, gender etc. However this is how things have gone:
We started at the same point on the pay scale, and theoretically continue in the same point. We have used a lot of childcare too. But there are always, always, extra meetings that start after 5pm, or that run late, or the meetings that require unpaid preparation at the weekend. One of us has to be there when the childcare closes, has to be there for the kids at the weekend. One of us has to say no to all the extra professional stuff essentially.
We’ve talked about it, considered sharing this burden, and ultimately agreed it made more sense for one of us to take the hit and the other to continue moving forward.
We remain on the same pay scale, but he gets the discretionary points, the credit for extra work, the promotion into management positions, and he is most certainly earning more than me now, 3 kids down the line.
By your example @BooFuckingHoo2 he has been (?we’ve both been) quite happy for both of us to continue to work with childcare and everything else...but make no mistake, his career has progressed beyond mine and he is earning more because I have taken the hit, because I make sure I am there at 5.59pm to collect the kids. And yes, he most definitely wanted children too. I consider the extra income that he earns family money, only achievable by him because someone else (me) picks up the slack in our family life. And that’s hard work too.
I see this all pattern around me. Medic-medic marriages are pretty common. I bet this exists in law and other professions too.
I’ve also sat on discretionary point panels too (that award bonuses for extra work out-with the usual job plan) and am aware that these bonuses are very much skewed toward men. Women just can’t add on extra work when they are (usually) the one who has to run to pick up the kids on time.
The differences in earning potential are not limited to SAHMs. Women may well run the world when it comes to anything important, but it appears this doesn’t come with an hourly rate.
