Spare a thought for the e-Jet drivers during this. Only last week being assured e-Jet isn't leaving.
No base protection in the EBA - union not wanting to get involved and the most senior of them only being high enough to bid for a MEL/SYD 737 command.
Pilots - who'd want to be one
If I was them, I'd wait it out for a while, more to come to this story I'd suspect.
