Eshlon, you are so right on the money with your comment.
I have seen some total morons survive VR/CR not because they are hard working and talented people, but because they are part of the furniture, or they know how to use the HR system to their advantage.
Once they survive they are then normally promoted out of danger to lead a project or some other bullsh1t non productive position.
Whatever way this is done it will never be fair and equitable to all parties involved. Never has been,never will be. It will be run the same way as training spots, the ALAEA can fight tooth and nail over the meaning of a word, but as they have shown in the last 12 months, it doesn't matter what is written in an EBA, to them it means nothing.
This sort of stuff should be handled by a third party organisation chosen by both parties, one that doesn't know anyone,or has nothing to gain or lose by making the decisions.
As long as management is involved, no one in the firing line will like they way it unfolds.
