Any NA based FO who signs on to COS08 is either 54 years of age, or medically retarded.
Let me see, yeah, I would like to sign up for a huge pay-cut. You are paying me too much money, so let me CUT MY OWN PAY. At least if the company was forcing it on the group, then you couldn't blame a guy for being under the new COS08.
I suspect the number of NA FOs signing for COS08 will be counted in one hand. And half will probably have done it by accident.
