Pretty bloody awful, at least according to Ned Resnikoff. The exception was the Chicago Teachers Union strike. As Ned states:
If there’s a common theme to the labor movement’s recent victories, it’s that they occurred outside of the American unionism model which has persisted since the second half of the twentieth century. The CTU strike was the closest thing to a mainstream labor negotiation, since it involved collective bargaining over a contract; but strikes are exceedingly rare in modern America, and CTU is an unusually democratic and community-based union. The fast food and Wal-Mart strikes resembled labor actions of the Gilded Age and the thirties more closely than any major union campaigns in recent American history. Even UNITE HERE’s explicitly electoral campaign focused on consolidating a permanent base of power within the state instead of rallying behind a single candidate.
For the large unions operating within America’s post-World War II status quo, the past year was a nearly unmitigated disaster. However, in low-wage service and retail workplaces—arguably America’s new economic center of gravity—labor was able to make some small but significant gains by reverting back to an older, more militant for of unionism.
I would generally agree with this analysis.
