>If your business fails due to a parental leave of all things, let me tell you, you were probably severely delusional about its viability to begin with.
Let's take an extreme case: a 1 person business. If I, the business owner, take parental leave then my business is pretty much guaranteed to fail. The rate gets lower the more employees and capital you have, because you can mitigate the risk, but many businesses are susceptible to this risk, because they simply don't have the resources to mitigate it. That doesn't really tell you much about the viability of the business. It says much more about the resources the business had available. Not everyone is born with a silver spoon in their mouth.
