It might be instructive to see what BA could have done:
1) They could have issued 90 day notice to all crew and a new contract. (source BASSA's QC in the High Court)
2) They could have imposed minimum crewing levels outside strike days. crewing levels aren't contractual (High Court again)
3) They could have applied for union de recognition on the basis of lack of support within the bargaining unit.
4) They could have taken away staff travel from all CC with the proviso that you get it back when you sign a new contract.
None of these have happened, are these the actions of an employer who wants to break the union? All BA (and the rest of us) want is an adult 21st century relationship with the union where common problems are recognised and shared.
