That's right Freight dog, the company wont be forced into giving A scales. The A scalers are just using that as an excuse to hide behind.
They could do the honorable thing a vote no, but I suspect the offer will be too good to pass up.
They could accept my proposed B scale +15% AND all the COS perks to stay here till 65 and it would be in a legally binding contract which they accepted,
there wouldn't be any "legal and operational implications"
Of course the selfish sods wont do that.
