Should there be a SANFL players union?

With some players getting paid part time wages with dedication required being required closer to that of a full timer should there be some sort of Players Union?
Clubs seem to be able to break contracts and dump players willy nilly yet when a lot of players want to transfer to another club to earn a similar living large transfer fees are thrown on their heads (my club is as guilty of this if not moreso), which I dont think is fair.
Should there be some sort of players union or if the transfer fees situation was worked out would that be the end of most of the problems?
I personally think if a player is not wanted by a club or offered a reduction in contract by X% they should be able to go wherever they want free of charge.
A Players Union might put more pressure on the SANFL upping the salary cap further or aboloshing it altogether too.
Thoughts?
