Lala Malone and the rest of the cabin crews' union leaders will evade any personal liability, of course.
I don't post often but the above caught my eye. The action was taken in the name of "Malone and others", not Unite or BASSA. This means that, officially at any rate, "Malone and others" will be liable for the costs.
The two questions which should really count are these:
1. Can "Malone and others" afford to cover BA's costs, both legal and losses incurred due to any associated action?
2. If not, will UNITE pay the bill for them?
If I were "Malone and others", I'd be feeling extremely vulnerable at the moment.
