I was under the impression that they asked the company to withdraw the impositions then re-negotiate ( my understanding from an off the record conversation was that now EVERYTHING would be open to discussion ) At the moment WW is waiting for the outcome of the Feb hearing before engaging in any meaningful talks.
I don't think BA can afford to remove the impositions - they need the savings NOW.
So would you not accept it if BASSA were to approach them now and say "OK, we will accept what you have done on November 16th as a vital measure to cut costs, but we want to discuss some proper bonus-type arrangements for when the situation recovers, which adequately compensate us for our part in both the recovery and future success of the airline".
