From the BBC article:
"Unite hopes a court hearing will take place next week. It says if the court rules in its favour and the changes are prevented from coming into force, it will review the strike ballot which is under way."
But if the court rules against it, would that not also require a review of the strike ballot? I mean why vote on possible strike action over something the court would then have ruled BA is within its rights to do? Is the union merely seeking temporary relief at this point? Or is industrial action permitted in the UK for more things than just mid-term, unilateral changes to Ts & Cs?
