We are in the realm of
opinion, and I don't have one
If they took away the "paid what you can hold," I'd leave the job. And I'd get paid what I would hold, which would be higher than my current seat.

From a company POV, they'd have serious trouble having SLIs if there was no pay incentive, particularly on NB fleets. As a pilot, I think we are better served with line instructors than DPS. You may have other feelings. I'm sure the company would love to get rid of all line pilot instructors. Huge cost savings

I'll let you have the last word
