This is a real concern(for me). It will dwarf the 3 holer 727FE jobs lost that was also a blip(taken as an isolated event) during previous careers. At least Delta has minimum pilots definition codified it in their PWA.

I had this discussion with my kids.... fortunately, one is in the "better than 50%" overall seniority which I couched as an informal goalpost to mitigate "black swans".

1. Off probation
2 Furlough proof(15% below min, 30% below optimum)
3 Top 50%(single pilot ops proof)
