It is not only BA cabin crew whom Mr Holley and his cohorts are sending over the abyss; dare I suggest, he is putting into jeopardy the current freedom and rights of all employees and their current right to exercise their right to strike by opening up the procedure to public and government scrutiny.
There are already some significant provisions in place which permit employers to sue a Union for carrying out industrial action where statutory immunity is not valid (i.e. an unprotected action):

The last paragraphs are especially relevant, where BA could sue Unite for up to £250,000, can sue Union representatives individually for organising unprotected pickets, and where individual passengers can sue the Union for losses incurred because of a failure to deliver services as a consequence of unprotected action; I can imagine BA is all over this.
Further backing for the position that Unite is unlikely to authorise any walk-outs.
