Earlier quoted context omitted.
That 12 weeks of unpaid leave is only for companies who employ more than 50 people, too. I expect most Americans work for companies smaller than that (and so don't get the leave) but I haven't checked.
Your expectation is wrong: https://www.nysscpa.org/news/publications/the-trusted-profes... "Since 2014...34.3 percent worked at small companies." And this is for "small" defined as It's also important to note that it's wrong to say that employees of small businesses "don't get the leave." Many small businesses will ofter leave to their employees without a federal mandate.
By "don't get the leave" I meant "aren't guaranteed the leave", of course.
