One thing to keep in mind. The airline is not only rapidly hiring pilots and cabin crew as they have been for years now, but they are also consistently hiring office staff and ground support staff to meet up with expansion rates. Not to mention the numerous daily resignation / terminations to keep up with.
Not only does this put a huge strain on the HR department, but even that department seems to be struggling to hold it's own.
And round and round it goes. No one really knows what's going to happen next.
