I think one of the problems now is that it’s extremely difficult to make any changes which would be perceived as a backward step. So for example it would be nigh on impossible for legislation to say the mother can have 9 months and then the father 3 (or lose the last 3) because you’d have women complaining that they were ‘losing’ because they’ve previously had a right to a year.
On the other hand if, when it was normal for women to have 3 months, an additional 3 months just for dad had been the offer, I think we’d have seen a much higher take up. Or likewise I remember by the time I had dc2, maternity leave had increased to 6 months. If at that point an additional 3 months had been added for dads, again, I think the take up would have been higher. It’s the fact that women have got used to a whole year, and until the legislation a few years back it was only the woman who could take it, so it’s hard to shift attitudes, even where it could benefit everyone in the family in terms of family dynamics.
I agree though that while it’s a financial disincentive for dads, it’s harder to encourage people that it’s a good idea. Though it’s important to remember to not just look at the immediate financial hit, because while the dad takes some of the leave, you’re saving on childcare fees for that extra few months. Also, I strongly suspect another knock on might be that more women would stay in work. If a woman is teetering between going back after ML or becoming a SAHM, it could easily swing it in favour of work if she knows she’ll have 3 months of being able to get up and off to work without the added pressure of getting the child up and out too, because dad is at home. And then once she’s been back in the workplace for 3 months, she’s more likely to continue.. hence far better financially long term because she’s staying in the job market, getting pension contributions etc.
I really believe there would be a lot of long term benefits to shared leave that aren’t immediately obvious, as well as the short term benefits.
