Let me recommend Trish Kahle’s Jacobin piece on the Miners for Democracy (1970s reformist United Mine Workers members) and the potential of energy workers embracing environmentalism. Brief excerpt:
Ultimately, the group of miners arguing for an energy workers union federation — or even a new union to represent all energy workers — were unsuccessful in transforming their union in that vision. This failure helped lead to the decline of the MFD, and along with it, the radical environmentalist vision they put forward.
The political space that had been opened up by the incredible levels of self-organization among rank and file miners allowed broad debate and agitation on issues like the environment. But as it became harder for workers to go on the offensive and the energy conglomerates continued to consolidate their power, miners found themselves fighting an increasingly uphill battle that left less and less room to fight for anything except survival.
Although they were some of the last workers to do so, the United Mine Workers did eventually face decline accompanied by the growth of conservatism. Today, rather than being seen as the vanguard of a movement to protect the land, miners are portrayed by many environmentalists as backwards, reactionary, and part of the problem.
I think this is pretty much correct for the UMWA, but in other industries, it wasn’t so much consolidation as it was capital mobility that undermined union environmentalism. The labor-green alliance she describes was not unique to the UMWA at the time. The Oil, Chemical and Atomic Workers were the pioneers here, but the International Woodworkers of America, International Association of Machinists, and United Steel Workers of America had pretty strong environmental records as well. She concludes by talking about union democracy as central to a labor environmentalism, but my own research on the IWA really doesn’t suggest this is necessary. For the IWA, it was the union leadership pushing the green message and the locals embraced it or didn’t depending on the issue. When there was rank and file resistance, it was against environmentalism, not for it. So in the case of the UMWA, the connection between union democracy and environmentalism was profound because it was so connected to the leadership’s indifference to workers dying of black lung and in accidents. But that’s very much not a universal thing.
Despite this quibble, this is an excellent article on the potential of energy workers embracing a green future, even if, understandably enough, how to get from Point A to Point B remains pretty hazy.
