Ok. What is CX going to do if none of us sign?
They have a mandate to reduce costs. Adhoc hotel rooms and PT's are not cheap. Let alone extending your duty to cover the overnights here and there requires more crew to handle the task. What is going to stop them asking you nicely to PX on the freighter? If it suits you.. do it! If it doesn't.. don't.
At the end of the day, I firmly believe in negotiation. But if they want to play hard ball, let them. What have you got to lose?
