I know many guys in the building industry around Perth and when it comes to union dominated sites, they have no choice but to be in the union. Technically they don't have to be, but unless they have no fear of a hammer falling on their head, then that is how it works. So in many cases, yes they can cancel their membership. But doing so means they are make themselves unemployable on all union dominated sites.
Myths, though I have disagreed with you many times in the past, I have always respected your technical knowledge, from which I have learned quite a bit. I'm not the one for name calling, so I have always taking you at face value - you are here to dispel myths about the NBN, not to play partisan politics.
However, in the last month or so I think you are adopting a very partisan stance. Very unlike you and making me question the independence of some of the data you produce, which I personally can't verify.
To some extent it has to be partisan, because the NBN is the policy of a political party, and the other party opposes it (although far less than they used to). Therefore a debate on the two policies must be somewhat partisan. The NBN is a typical Labor policy (ie Govt build it for everyone). The coalition's policy used to be typical Coalition (ie leave it to the market), although now it's basically a cheaper version of a Labor policy (ie the Govt is still building it for everyone).
That said, the discussion has moved off on a tangent, mainly because I'm amusedly perplexed by Caliope's notion that union political donations are examples of self-serving corruption, but business political donations are entirely selfless.
I guess it has got to be hard knowing that your puppy is being replaced by a kitten.
I remember having a tanty as a little tot when this happened to me.
I don't think it would happen to me nowadays.

Nobody would be happy about losing a puppy for a kitten. Everyone knows dogs are better than cats.
