I think it is telling that last time round BA did not go to court rather they informed the ERS and union of flaws in the ballot and the union pulled the strike. Given this and that the current ballot is likely to be within the law all that leaves is the protection or otherwise. Now as BA did not go for an injunction and seemed prepared to let the union strike, merely setting them up for financial liability, perhaps this is an indication of how BA will act this time. Certainly VCC training has been massively ramped up in recent months, suggesting that BA expects a strike to go ahead.
If UNITE are stupid enough to think BA will do nothing they deserve all they get. Industrial Darwinism may be a force at play here - the dinosaur mass extinction could be mere days away. Crippling UNITE the union financially would be a smart move for BA; removing the threat of this cancerous growth interfering with the business forever.
