Indeed, we haven't seen any documented indication that BA have approached the ERS.
I don't think that Mr Mcluskey has said that BA have approached the ERS, although he wants us to believe BA have.
Perhaps a word between the QC's, or even just a word from the Unite QC, has indicated that, legally, Unite are on thin ground protecting their finances and members (yes in that order) and Unite are trying to escape from the position they find themselves in.
I imagine Mr Holley, and others, are privately seething as Unite have once again pulled the wool from under their feet.
Interestingly, I see that BASSA has taken moves to protect their own finances.
Is this Unite telling them that they do not want to put their money on the BASSA horse?
