The question always comes back to encouraging people to vote. Even in a closed shop there is no guarantee everyone will vote, or vote according to their own conscience and belief. Closed shop is not, nor ever has been the answer.
The apathetic, the "it's OK, the others will make the right decision for me" and the downright "couldn't give a toss" brigades need to be convinced that their vote matters.
This dispute has been prolonged, not by Bassa branch officials intransigence or WW stubborness, it is entirely due to the apathy of the majority of Bassa members allowing a minority of their brethen to dictate policy.
