I think we're getting into the realm of NHs needing to understand the difference between healthy attrition and attrition. Attrition overall has always been viewed because no airline has been in the position of unhealthy attrition in 20+ years. But the rate at which we lose senior FOs and junior captains is astoundingly bad for the airline model, and unsustainable, as has been posted and talked about dozens of times.

If I'm a NH, I want there to be movement, not just attrition. A savvy NH may understand that in 12 months there will be no captains left to operate the jet, and being 70% in domicile as an FO doesn't do you any good when the other seat is only half staffed and we're looking down the barrel of a recession.
