Colonel White,
These people are not BA employees and have no axe to grind. They are showing genuine concern for a contract that does have a layoff clause in it.
It also has a one week notice clause by BA but the crew member has to give 4 weeks and it also has a clause in it that the crew can be used to work on the ground if BA requires it.
Many people are signing it because they want to be cabin crew but many who work for other airlines, like Virgin, are worried about these clauses, as are some of the BA temps.
I am sure there will be a never ending supply of people that want to be crew but I can assure you that some people have been put off by these clauses and some people have actually left the training courses already because they are unhappy with the Mixed Fleet regime and that is something that I don't think has ever happened before.
