Wouldn't that be just moving the issue to another source?
That is what I am doing. I have a main job, I do some freelances and I invest my money. I am lucky to be in a "high end" sector with many opportunities, but I can't expand and expand my revenue streams, we have a limit don't you think?
Sure, we have economic limits, but those limits aren't totally defined. My point is that the union has a limited utility. Don't count on them. That isn't to say that your union should not be fighting the good fight.
