So, in many European countries, fathers and mothers have a right to substantial amounts of parental leave. Like a year or more. In all of these places small businesses exist. In Sweden, with very extensive parental leave [1], there is a large number of start ups. So obviously, empirically, you must be missing something.
Generally speaking, if your employees care about your business (and getting their job back after the leave) they will not take decisions that destroy this business. Some laws will also vary depending on company size, though parental leave is just such an obvious fundamental need and right that I am not aware of a country where it does.
You might not think of yourself as immoral, but your post is definitely sexist, and I find the viewpoint you take towards your potential employers deeply unethical. Because people like you sometimes end up with power we need democratic states to fight back and keep a sense of perspective.
[1] "New parents in Sweden are entitled to 480 days of leave at 80% of their normal pay. That’s on top of the 18 weeks reserved just for mothers, after which the parents can split up the time however they choose. Swedish dads also get 90 paid paternity days reserved just for them. Out of these 480 days, 60 must be taken by the father or else all are lost. This leave can be taken by the month, week, day or even by the hour."
So fathers are forced to take more paternal leave in Sweden than mothers get in the US.
