In recent times quite a few UM pilots have applied to other airlines and been accepted, and for this reason UM went on a recruitment drive a few weeks before the strike started.
The ZS reg a/c was contracted to supliment the domestic routes about a week before the strike started as the MA60 was down for major inspection and the other two were down for repairs. The second ZS reg a/c one came into service after the strike started.
If the pilots leave or take alternate employment, they will certainly lose ALL that is owed to them, and that is why I think a lot of them are hanging on. Once paid though, you may well see a large exodus out of UM!!
Heard a rumour that discussions are on going, with UM management saying 'come back to work and we will talk' and the pilots saying 'talk first then we come to work'!!
For the record...the standard of UM pilots is still high!!!!
