Well, I'm pretty sure that any investor willing to put a couple more millions into SkyEurope at this time will have some vague idea of what he is doing... not necessarily, of course, but probably.
At the moment there is not much else to choose from for SkyEuropeans anyway. As for the "flying for free": The company needs everyone to cooperate now. If people were to refuse to work at this stage, then you probably couldn't blame them for it, but it would mean the sure end of everything.
The best that can be done now, is to keep working hard and hoping for a christmas-miracle. The worst that can happen is, you work for free for yet another month or two, instead of losing your job straight away.
Keep going, SkyEurope!
