While LowPhyler's description of how the final pay rates and profit sharing part went agrees with your assertion here, my understanding is that the MEC was kept in the loop throughout the process as to the rest of the contract. They received regular updates as to what had been agreed upon, and what had not. As I understand it, there was some amount of redirection when certain desired items could not be achieved in their original form.

Saying that the MEC played no role larger than that of a stringed orchestral instrument during that time is very different from what I've heard.
