My wife is an L&D nurse. With our first son, she wanted to take off the maximum amount of time. FMLA is 12 weeks, but Tennessee gives you four months (I know, Tennessee being progressive, who knew?).
HR turned the four months into 16 weeks. Absolutely could not get more than 16 weeks (four months is over 17 weeks, fyi). Also, FMLA (and Tennessee's version) does NOT have to be taken all at once, nor does it HAVE to start the day the baby is born.
Seeing as how she worked at a hospital, and delivered at a different hospital that was part of the same network, her manager was able to check the records at the other hospital and see when my wife was admitted as a patient (simply looking at a list of names is not recorded, looking at their files would be, though for all we know they may have looked in her files). We know because she did not tell a single one of her coworkers when our baby was born, and a congrats package (think it was some flowers) was delivered from her work. I know many will think "ahh, that's nice" but it was more like "we know you had your baby, so your FMLA starts now." She was technically on vacation at the time, due date was the next week which was when leave was scheduled to start. Of course they moved it back a week.
I know, it's not THAT big a deal, it's only two weeks. That's kinda the point though, they fought to keep her from getting those two weeks. You could tell this just wasn't a normal thing, taking off the maximum time allowed after the birth of a baby.
Australia is like night and day. I don't know the cut-off, but if you work past a certain week during pregnancy, you have to have a doctor's note (wife worked up to a few days before our first son was born in TN, no note needed). The Australian government pays you 18 weeks at minimum wage (which was $17-something I think). Her work also had 10 weeks maternity pay at her average salary. It was not unusual at all to take off a year. My wife could even extend it another year if she wanted (she did by a few months).
And I haven't even gotten into costs. Around $100 for the entire pregnancy, and that was for one uncovered test (which we might have been eligible for a rebate, but we were still new to the whole system). She was in the hospital for about a month. Great care. Probably didn't hurt that she was a midwife there, but still.
