Well, we shall see the outcome of the ballot. I am sure the debate will swing back to the minority deciding the future of the majority soon enough.
As I have said before, change the law and allow full negotiating rights to all employees. This will not bring the country to a stand still. It will still need unions and the funds that they have, to counter the financial strength of industry.
Another example of how the law requires union membership, is the right of representation. Would you trust to luck whether you have a legally trained and experienced colleague, that could accompany you in a disciplinary?
