Use It or Lose It
If our government ever succeeds in establishing a paid parental leave policy, my biggest fear is that it will be scoffed up by mothers. We fathers will be left with crumbs, just like the paid leave policy in New Zealand that allows mothers to share all or part of their 14 week parental leave with fathers - only 1% do so.
And where will we be if mothers take all the paid leave? In some ways, worse off than we are today. Parenting will be just as mother-centric as ever, and mothers who get, say, 8 weeks of paid leave will just be that much more financially able to take more leave after the 8 weeks are up. More leave equals more time as the sole parent with a couple's new baby - which equals more expertise by the mother. A father has no chance to catch up!
I much prefer a "use it or lose it" parental leave policy. Take Iceland's for example. Here mothers get 3 months paid leave, fathers get the same, and the couple gets an additional 3 months to divide as they wish. The result? Fathers take 35% of the parental leave. That means they are taking their 3 months and just a tiny bit more. Mothers are still hogging the shared leave time, but those fathers have 3 months of parenting under their belts. A beautiful thing!
So, if someday we are awarded 8 weeks of paid parental leave, I would portion off at least a few of them to the guy as "use or lose." Even crazier (and probably not possible), I'd make the paid portion of a man's paternity leave only valid if taken sequentially (not simultaneously) with his wife's leave.
