The war on collective bargaining is already several decades old and is now being waged against public sector unions. The Republican Governor of Wisconsin wants to eliminate the ability of public sector unions to engage in collective bargaining. Paul Krugman thinks this effort will mark America's transition back to oligarchy:
Why bust the unions? As I said, it has nothing to do with helping Wisconsin deal with its current fiscal crisis. Nor is it likely to help the state’s budget prospects even in the long run: contrary to what you may have heard, public-sector workers in Wisconsin and elsewhere are paid somewhat less than private-sector workers with comparable qualifications, so there’s not much room for further pay squeezes.
So it’s not about the budget; it’s about the power.
In principle, every American citizen has an equal say in our political process. In practice, of course, some of us are more equal than others. Billionaires can field armies of lobbyists; they can finance think tanks that put the desired spin on policy issues; they can funnel cash to politicians with sympathetic views (as the Koch brothers did in the case of Mr. Walker). On paper, we’re a one-person-one-vote nation; in reality, we’re more than a bit of an oligarchy, in which a handful of wealthy people dominate.
Given this reality, it’s important to have institutions that can act as counterweights to the power of big money. And unions are among the most important of these institutions.
Andrew Sullivan has a nice series of links to stories illustrating various aspects of the issue.
