A man cannot serve two masters.
You are either working for the corporation that pays you (your employer) or the corporation that you pay into (your union).
Unions are now nothing more than corporations that make their profits from extorting money from their members in order to extort money for the members from the member's employers. This extortion racket is now called collective barganing.
Unions are a counterbalance to the concentration of power in corporate hands. As such, they are CRITICAL to the proper function of market economy. Had you or any of the people I see parroting this position had any economic education, you would know this. It isn't 'liberal' economic theory, it's econ 101. Don't take my word for it, though. Ask Adam Smith, the founder of market theory. He understood the organizational power of industry, and the need to counterbalance that power:
"People of the same trade seldom meet together, even for merriment and diversion, but the conversation ends in a conspiracy against the public, or in some contrivance to raise prices."
It is, by the way, because of this, among other reasons, that the free market unregulated is just as broken as communism. Regulation is not just necessary, it's salutary - a point lost on the supply-side 'economics' free market nuts. The US economic system is NOT free-market, but mixed-market, AS IT SHOULD BE. Supply side 'economics' is politics, not economics, as George Bush senior rightly noted when he referred to it as 'voodoo economics'. The right has been using this fake brand of economics to slowly strangle the middle class, pushing the US further from democracy and closer to oligarchy. The attack on the Wisconsin unions is just the latest chapter.
In case you find the above quote too ambiguous (Smith is talking about price fixing), here's more on the power imbalance.
"I.8.11
What are the common wages of labour, depends every where upon the contract usually made between those two parties, whose interests are by no means the same. The workmen desire to get as much, the masters to give as little as possible. The former are disposed to combine in order to raise, the latter in order to lower the wages of labour.
I.8.12
It is not, however, difficult to foresee which of the two parties must, upon all ordinary occasions, have the advantage in the dispute, and force the other into a compliance with their terms. The masters, being fewer in number, can combine much more easily; and the law, besides, authorises, or at least does not prohibit their combinations,*10 while it prohibits those of the workmen.*11 We have no acts of parliament against combining to lower the price of work; but many against combining to raise it. In all such disputes the masters can hold out much longer. A landlord, a farmer, a master manufacturer, or merchant, though they did not employ a single workman, could generally live a year or two upon the stocks which they have already acquired. Many workmen could not subsist a week, few could subsist a month, and scarce any a year without employment. In the long-run the workman may be as necessary to his master as his master is to him, but the necessity is not so immediate."
The sooner the 99% of conservatives for whom republican policies spell eventual economic slavery realize that they're being suckered, the sooner we can get back to having a serious political debate in this country. The right to unionize should be a constitutional right, at least if you're a fan of market economics. This WOULD cause serious issues with foreign trade, though...this is not a magical fix-all (at least not until the right to unionize is realized globally - don't hold your breath).
Think I'm playing up the class warfare angle here? Consider that virtually all of the gains in worker productivity in the years since Reagan took office have gone to the owners, not the workers. I suggest all you conservative union-haters give the following article a thorough read, though the productivity data I'm referring to is about halfway down the page:

The right has been waging war against the middle class since long before Reagan. They'll continue to succeed until you all wake up. The success the right has had in getting you all to pillory anyone pointing this out as a 'communist' is disheartening. Democracy only functions properly with an educated electorate.
