After working for the same company for 10 years doing very remote-able work, I “earned” the opportunity (read: developed a strong persoanl relationship with my boss) to take a lump of vacation time (~30 days) to spend with my newborn kids, and then the right to work half and half remote/onsite after that. I was lucky to be at my job long enough to accrue vacation that quickly, and that my daughter was born toward the end of the yar, so I was able to bank way over my rollover limit. And that’s at an early childhood focused non-profit. America has a ways to go on this front. NY’s parental leave policy is a step in the right direction, though it kicked in just after my makeshift paternity leave ended.
I actually think part time work is really great for new parents, allowing your to keep a toe at work, and give you a minute to miss your kids, while not feeling like there are huge swaths of their formative years you’re missing. It saves a boatload on infant care too.
