That should be your first clue. CX offer this contract, CoS08, but don't like some of what is in it. So you have to sign that away to take the job, in this case PX on the freighter. When I joined, I was told to sign such that I might have to fly the freighter "from time to time" even on passenger terms. All these little take backs are indicative of what you can expect your whole career, a company that continuously erodes your contract both overtly and via inflation. It really is a dog's breakfast in CX these days. Those of you telling yourselves otherwise are lying just to feel better.
