Not so sure with Unite - the relationship was with TW, not LM. And TW has ultimately failed to deliver anyway. I think TW shaking hands and then washing them has already done the damage.
Hitting Unite would help solve the BASSA problem as the follow up of sacking strikers would mean BASSA getting close to derecognition. And it might make Unite take a greater interest in BASSAs activities.
All conjecture. Sad day for all at BA. Good luck to Betty Girl et al who want to work for the company.
