I don't think they are just considering it, from the mood of the CC I would say its a dead cert! The proposal is exactly the same as the last one which was rejected and to quote our manager in a recent Q&A, "why would you be happy to accept it this time when last time you voted to strike?" Intentionally provocative?
It appears to me that neither side has any interest in negotiation or compromise. If no-one is prepared to move their position then no progress can ever be made. We need a smiley with two heads banging together!
