So as Unite is planning on taking legal action against BA, let's have some details.
Which firm of lawyers is Unite using? What's the name or the QC taking the case? How is the cost of litigation (at least a seven figure sum being funded)? As the case will take many years to resolve what will cabin crew do in the interim as Unite won't accept BA's offer to restore ST for commuters? Have court papers been filed? Who are acting as witnesses?
As Unite is now pressing ahead with litigation answers to these questions should be readily available.
