Disgusting though not surprising given the airline's anti labour, union busting practices. They're not sorry, just sorry that they were caught.
I like to hope that a "smoking gun" like this would result in some actual action by the regulators, but we all know that isn't going to happen.
I'm a big supporter of the EU but situations like this where a company can choose to employ crew through a crewing company in the EU state with the lowest labour protections, base them in another country entirely and then complete against other airlines who actually do treat their staff half decently, shows that the current laws are completely unfit for purpose, especially as far as airlines go.
