There is also no chance of senior crew voting to accept pay cuts to save Normantons job (as an example)
I don't think they'll be asked to vote on anything. Already a process to manage crew numbers with the stand down process.
The only pilots who will need to be RIN'd anywhere by March '21 are the 747 pilots, and I believe that their numbers are approximately equivalent to the probable retirements to that date, and any excess from that can be easily managed. There'll probably be an increase in retirements as a result of this slowdown.
With a long term view, the company knows 5 years from now they will need pilots of normanton's era (joined within the last 3 years). It is in their long term interest to ensure the most junior pilots remain with the group in some fashion.
