Working overtime for A$A is like giving an alcoholic a drink. The sad fact is without TIBA's and more importantly the publicity about TIBA's, nothing would have been done (even if it is to little too late). I was always prepared to give up a day off to keep the system working while it was a short term problem, but for years it seems to have been policy rather than predicament causing OT.
There is no perfect solution. Closing airspace is shafting the public at best, dangerous at worst. However, if you keep wallpapering over the cracks, they get bigger, making 'the big one' more and more likely.
As for not leaving your colleagues alone, as much as I dislike working with Mr TIBA, it's better than a coworker who hasn't had more than a few hours sleep in the past few days.
