Caribbean boy says:
This won't happen because any dismissal is illegal in the 12 weeks of industrial action so long as it is protected strike action. Protection is only possible where a proper secret ballot has been conducted in a 'lawfully organised' way. The employer cannot sue the union, and striking staff are protected from dismissal for a period of up to 12 weeks.
There have been suggestions in recent posts that ballot papers have been sent to non-members, so the chances are that BA will be able to invalidate this ballot just like the first one. The questions are whether they will do so, and if they do, whether it will be before or after the strike starts.
