Methinks Barnstormer et al are being rather optimistic in believing that if BA fails, BA2 will quickly rise from the ashes and employ everyone back in their old positions.
Firstly the slots will be up for purchase to the highest bidder:
If you are lucky, Virgin and other companies will buy many of the slots from the receivers and ex BA pilots will be able to find work at the bottom of their seniority lists.
If you are unlucky, the Americans will raise the cash and operate the slots with N registered aircraft for which you will not be qualified by licence or Nationality.
Secondly, if the receivers manage to continue the operation whilst they restructure, this will be on a much smaller scale and cost basis that the present operation. It won't be a take-over where your terms and conditions are protected.
Perhaps half a loaf....?
