If I may add to that, the significance of these statistics is that the way the union is structured only full union members have the vote and representation in their terms and conditions of employment, which is why the casual statistics cited are dreadful.
But worse than that are the statistics cited within the union ranks, because it is this 1% that is vying for control of terms and conditions, which they don't have, and that is why you find, from an election perspective, that there are no women in the ILWU executives.
