I don't have proof. From what I have seen and read, it would be 3-10 humans who didn't show up to work over a weekend. The airport couldnt manage the planes leaving with such low staff and the ones landing took priority. Everything else was just grounded until further notice. It seems difficult to me to prove, that a few incredibly important people, all called in sick on the same weekend. The effect would be massive, even on a small company.
