I have not had to deal with an employer going bankrupt (yet...), but I can hardly imagine how much stress this puts on all of the staff. How will they pay their bills and mortgages, what will happen in a month, three months, six months, etc.
I would expect (and hope) that many pilots who do not have a significant other that makes a good living individually and/or a large stash of cash saved for such situations would be under huge amounts of stress and should be calling in sick in this type of situation where you know your employer is bankrupt and you have no idea where you will end up, yet you are still expected to go to work every day as if nothing were amiss.
