Most of the large companies I worked for had 12 weeks paid vacation and then you could do an additional 12 weeks which wasn't paid for the primary care giver. Otherwise, as a non-primary, you still got 2 weeks paid.
Also, I remember several female sales people abusing the system pretty well. They'd get within a month or so of their due date, then go to the doctor and get mandatory bed rest. Company would send them home and keep paying them 80% of their commission plus their salary based on the last three months of their commission rates.
I also saw a lot of guys claiming they were the primary so then both parents could get their 12 weeks of paid time off to spend time with the newborn together.
