For whatever its worth. The Japanese papers are reporting that bankruptcy does not give an employer the right to terminate employment contracts with employees. If this is true, then it is unlikely any Japanese non-contract employees will find themselves involuntarily out of work.
If that indeed is the case in this situation, I would assume that anybody that leaves JAL will do so voluntarily and with a nice separation package. I would also assume that there will be very little political or social pressure to ensure that these people are integrated into another airline such as ANA, after leaving JAL voluntarily with a nice chunk of change that has indirectly come from the government coffers.
Generally speaking, I would be surprised if too many pilots who are not nearing retirement age would be interested in accepting such an offer....
All that to say.... I wouldnt expect a long line of furloughed Japanese pilots from JAL looking for work just yet....
