I strongly suspect that they did experience this sort of &quot;evaporative cooling&quot; of workforce quality when they made that decision (or quietly reversed the paycut with targeted &quot;raises&quot;).<p>Ditto for GM when they offered all union employees the same (formula for) buyout from their contracts -- the best ones take it and leave because they&#x27;d get the money and the new job; the poor performers know they can&#x27;t last anywhere else and stay on.
