Negativity in the flight deck or in any corporate setting does not happen in a vacuum. It speaks to an underlying HR issue, and it is that corresponding company's management's responsibility to determine the reason and make a good faith effort to resolve it.

Dragging out negotiations, presenting lowball offers, and causing pilot QOL to deteriorate to the point where it was becoming unbearable was guaranteed to have consequences.

That however is not the main reason why new hires are leaving, and trying to scapegoat it as such is just a tad disingenuous.
