Volunteers
The fact that thousands of people, including pilots, volunteered to become CC, plus more willing to help break the strike on the ground, is highly significant. There is little support for CC from other BA employees and a majority of the public don't support them either. What a change from three months ago when the CC were generally well-regarded.
As most people like to be liked, I feel that cabin crew will hate the feeling of isolation, especially if they go on strike.
