I left Unions out of my little rant there - I've never understand why in the Unions (and in Politics, maybe?) that the worst people of each profession are chosen to lead. Many Unions around here are quasi-corrupt organizations whose leaders only care about money and their own self-imporance.
I think you answerd your lack of understanding in sentence one with sentence two - the worst often become the leaders because they are busy stabbing people in the back and trying to get away with doing the least possible while the good ones are actually busy teaching their students or doing whatever their particular profession actually requires. It's surprising how much effort people will put in to ensure they can be lazy, lol.
