maybe 50 guys will sign. They will all be people with a commute and an expectation that they can tweak the system.
the reality is that they will be screwed. Many people will not sign anything without a clear benefit. In addition there is a sizable minority who will sign nothing because they are required to actually do something.
So Cathay ends up with 50(or 60 or?) guys who want to PX 168 hours a month on the freighter. Those guys will end up with some interesting rosters!
You would have to be stupid to sign this.
