How will your kids have stability in their life if their mum (or dad, sorry not sure) is on permanent standby due to another BA imposition?
Always remember that the number of crew on any aircraft above and beyond the minimum as set by the CAA is the company's business and tempered by agreement NOT contractual binding.
Another little gem from the all knowing wobble2plank... Would the case be going to court if they weren't contractual? How the hell would you know something that the top level lawyers at UNITE don't?!
