Well the timber workers don't care about a "T" in the name, so a silent "M" should mean nothing in the big picture, the point is that the rank and file members are represented against greedy selfish employers who would have everyone without a tertiary or university education in the poor house!
PS:- I have seen it, been involved in it, we the humble worker mean nothing to a boardroom Chairman who drives a Rolls Royce with a chauffeur and lives in a multi million dollar mansion, paid for by bloody low skilled workers, well any bloody voice is better than no voice!
